AXIAL STRENGTH AND TIGHTENING TORQUE - TYPES LAC/LAS/LA4

(1) All LAC, LAS and LA4 locknuts have axial strength exceeding the minimum tensile strength of 180 ksi/Property Class 12.9 screws. Contact techsupport

regarding assemble strength for higher strength screws.

(2) Tightening torque shown will induce preload of 65% of locknut minimum axial strength with K or nut factor is equal to 0.20. In some applications

tightening torque may need to be adjusted based on the actual K value. All tightening torques shown are based on 180 ksi/ Property Class 12.9 screws.

For lower strength screws the tightening torque is proportionately less. For example, for 120 ksi screws, torque is 67% value shown. For 900 MPa screws

(Property Class 9.8) torque value is 74% of value shown.

A NOTE ABOUT 400 SERIES FASTENERS FOR STAINLESS STEEL PANELS

In order for self-clinching fasteners to work properly, the fastener must be harder than the sheet into which it is being installed. In the case of stainless steel panels,

fasteners made from 300 Series Stainless Steel do not meet this hardness criteria. It is for this reason that 400 series fasteners are offered (Types A4 and LA4). How-

ever, while these 400 Series fasteners install and perform well in 300 Series stainless sheets they should not be used if the end product:

•

Will be exposed to any appreciable corrosive presence.

•

Requires non-magnetic fasteners.

•

Will be exposed to any temperatures above 300˚F (149˚C)

If any of the these are issues, please contact

for other options.

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing proper

seating of fastener as described in the installation steps. Other performance values reported are averages when all proper installation parameters

and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect performance. Performance

testing this product in your application is recommended. We will be happy to provide technical assistance and/or samples for this purpose.

(2) For LAC, LAS and LA4 nuts, thread locking performance is equivalent to applicable NASM25027 specifications. Consult document PEM-REF25027 for details.

Prepare properly sized mounting hole in sheet. Do not perform any secondary

operations such as deburring.

Place fastener into the anvil hole and place the mounting hole (preferably the

punch side) over the shank of the fastener.

With installation punch and anvil surfaces parallel, apply sufficient squeezing

force until anvil contacts the mounting sheet. Drawing shows suggested

tooling for applying these forces.

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing

proper seating of fastener as described in the installation steps. Other performance values reported are averages when all proper

installation parameters and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect

performance. Performance testing this product in your application is recommended. We will be happy to provide technical assistance and/

or samples for this purpose.

Prepare properly sized mounting hole in the sheet. Do not perform

any secondary operations such as deburring.

Place the barrel of the fastener into the anvil hole and place the

mounting hole (preferably the punch side) over the shank of the

fastener.

With the installation punch and anvil surfaces parallel, apply

squeezing force until the flange contacts the mounting sheet. The

sketch at the right indicates suggested tooling for applying these

forces.

INSTALLATION NOTES

•

For best results we recommend using a PEMSERTER®

press for installation of PEM Types B and BS fasteners.

PEM® SELF-CLINCHING NUT SELECTOR GUIDE

Thread Mask

PEM® Blu-Coat™ thread mask is available for applications where hardware is installed

prior to painting. During assembly, the threads of the mating hardware will remove

paint, electro deposited automotive under coatings, and weld spatter upon application

of torque. PEM nuts can be specially ordered with thread mask applied.

“BC” suffix will be added to part number to designate Blu-Coat thread mask to fastener.

S-RT™ FREE-RUNNING

Free-running locking feature allows screw to turn freely until clamp load is applied. If the tightening force is removed, these nuts no

longer provide any torsional resistance to rotation.

•

Resistant to vibrational loosening.

•

Back side of panel is flush or sub-flush for screw installation.

•

Locking feature reusability is not affected by

number of on/off cycles.

•

Uses same mounting hole and installation

tooling as standard S™ nuts.

•

Recommended for use in steel or aluminum

sheets HRB 80 / HB 150 or less.

NEW!

The graph represents the clamp load of the joint versus the

amount of cycles during transverse vibration testing for an

S-RT™ free-running locknut, a standard hex nut and a hex nut

with a split ring lock washer.

Testing conditions:

Transverse vibration testing.

M6 thread size nuts, average of 30 pieces.

Clamp load applied using metric property class 10.9 screws.

Nuts tested until loss of clamp load or 2,000 cycles is reached.

SMPS™ NUTS

(1) Head size is adequate to ensure failure in threaded area when tested with industry standard tensile bushing diameter.

(2) Tightening torque shown will induce preload of 70% of minimum axial strength assuming K or nut factor is equal to 0.20. In some applications tightening

torque may need to be adjusted based on the actual K value. All tightening torques shown are based on 180 ksi/ Property Class 12.9 screws. For lower

strength screws the tightening torque is proportionately less. For example, for 120 ksi screws, torque is 67% of value shown. For 900 MPa screws

(Property Class 9.8) torque value is 74% of value shown.

TORQUE-OUT TEST

Pushout tests shall be performed from the grip or shank side of the

installed fastener. An axial load shall be applied to the fastener as

shown using a hardened test screw, while evenly supporting the test

strip around the fastener. The typical position rate is .25” / 6.35 mm per

minute. Dimensions are identified per PEM Bulletins where “E” equals

head diameter and “T” (or “L”) equals head height. The pushout force

is measured using a force or compression tester with a range that will

cover the expected forces.

Torque-out tests shall be performed from the shoulder or head side

of the installed fastener. Torque shall be applied to the fastener in the

manner illustrated, using a hardened test screw and washer, while

firmly holding the test strip. Test screws should be of sufficient tensile

strength to resist thread stripping. A minimum of two screw threads

must extend beyond the fastener.

select the proper fastener material to meet corrosion requirements.

make certain that panel material is in the annealed condition.

make certain that hole punch is kept sharp to minimize work hardening around hole.

provide mounting hole of specified size for each fastener.

maintain the hole punch diameter to no greater than +.001”/.025 mm over the minimum recommended mounting hole for type SP

nuts into stainless steel sheets.

install fastener into hole punch side of sheet.

make certain that shank (or pilot) is within hole before applying installation force.

make certain that fastener is not installed adjacent to bends or other highly cold-worked areas.

apply squeezing force between parallel surfaces.

utilize recommended installation tooling when installing fasteners.

apply sufficient force to totally embed clinching ring around entire circumference and to bring shoulder squarely in contact with sheet.

“DON’TS”

DON’T

attempt to install any self-clinching nut other than types SP/SMPP fasteners into a stainless steel sheet.

DON’T

install steel or stainless steel fasteners in aluminum panels before anodizing or finishing.

DON’T

deburr mounting holes on either side of sheet before installing fasteners – deburring will remove metal required for clinching

fastener into sheet.

DON’T

install fastener closer to edge of sheet than minimum edge distance indicated by manufacturer – unless a special fixture is

used to restrict bulging of sheet edge.

DON’T

over-squeeze. It will crush the head, distort threads, and buckle the sheet. Approximate installation forces are listed in

performance data tables. Use this info as a guide. Be certain to determine optimum installation force by test prior to

production runs.

DON’T

attempt to insert fastener with a hammer blow – under any circumstances. A hammer blow won’t permit the sheet metal to

flow and develop an interlock with the fastener’s contour.

DON’T

install screw in the head side of fastener. Install from opposite side so that the fastener load is toward sheet. The clinching

force is designed only to hold the fastener during handling and to resist torque during assembly.

DON’T

install fastener on pre-painted side of panel.

INSTALLATION

Prepare properly sized round mounting hole in

sheet. Do not perform any secondary operations

such as deburring.

Place fastener onto the anvil and place the

mounting hole over the shank of the fastener as

shown in the drawing.

With installation punch and anvil surfaces

parallel, apply sufficient squeezing force only to

embed hexagonal head flush in sheet. The metal

displaced by the head flows evenly and smoothly

around the back-tapered shank of the fastener,

securely locking it into place with high pullout

resistance while at the same time, the embedded

hexagonal head provides high torque resistance.

PEMSERTER® Installation Tooling

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing proper

seating of fastener as described in the installation steps. Other performance values reported are averages when all proper installation parameters and

procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect performance. Performance testing

this product in your application is recommended. We will be happy to provide technical assistance and/or samples for this purpose.

(2) Failure occurs in screw stripping using a 60 ksi screw and the shortest shank length fastener.

(3) Torque values shown will produce a preload of 70% of axial tensile strength with nut factor “k” equal to .2. Threads may strip or head of the F nut may bend and/

or fail if screw is over-torqued beyond these values or if actual k value is less than .2.

MATERIAL AND FINISH SPECIFICATIONS

PEM miniature fasteners must be installed by a force applied through parallel

surfaces. Since force must not be applied to the barrel, a cavity must be used in

either the punch or anvil so that the installation force is applied to the knurled collar.

“D” dimensions for the punch or anvil cavity are given in the tables on page 3.

INSTALLATION

Prepare properly sized mounting hole in sheet. Do not perform

any secondary operations such as deburring.

Insert fastener into the anvil hole and place the mounting hole

(preferably the punch side) over the shank of the fastener as
shown in the drawing.

With installation punch and anvil surfaces parallel, apply

squeezing force to the knurled collar until knurled collar is flush
with top of the sheet for sheets .060”/1.5mm thick and up, or
until shank is flush with the bottom of the sheet for sheets
.040”/1mm to .060”/1.5mm thick for FE/FEO nuts.

PEMSERTER® Installation Tooling

INSTALLATION RECOMMENDATION

In applications for sheet thicknesses between the two ranges (see “Sheet
Thickness” on page 3) use the fastener with the larger “A” dimension. For
example, if you want a #4-40 thread and your sheet thickness is between
.045”/1.14 mm and .059”/1.49 mm, you should use FE or FEX nuts. This is
not recommended installation practice, but in this case if it is necessary, you
should install the fastener so that the bottom of the shank is flush with the
underside of the sheet (instead of having the top of the knurled collar flush
with the top of the sheet). When this method is used, care must be taken to
protect the fastener against crushing which would damage the threads. This
method will also result in reduced pushout and torque-out values.

(1) Axial strength for nuts is limited by knurled ring strength.

(2) Screw strength level shown is the minimum needed to develop full nut strength, higher strength screws may be used.

(3) Tightening torque shown will induce preload of 65% of locknut minimum axial strength with K or nut factor is equal to 0.20. In some applications

tightening torque may need to be adjusted based on the actual K value. If screw strength is less than the value shown, tightening torque should be

proportionately reduced by multiplying the torque shown by the actual screw strength over the screw strength shown. If higher strength screws are

used, torque is not adjusted upward because assemble strength is still limited by locknut strength.

location of the mating fastener during assembly

and protects the first thread of the stud during nut

engagement. This feature is available on Types FH, FHL,

HFH, HFE, HF109, HFG8, TFH and THFE studs.

(1) For “L” refer to type stud lengths.

(2) Maximum dog point diameter is .003” / 0.08 mm less than

minimum minor diameter of 2B or 6H nut threads.

OPTIONAL DOG POINT FEATURE

OPTIONAL THREAD MASK

PEM® Blu-Coat™ thread mask is available for applications

where hardware is installed prior to painting. During

assembly, the threads of the mating hardware will remove

paint, electro deposited automotive

under coatings, and weld spatter upon

application of torque. PEM studs can

be specially ordered with thread mask

applied.

“BC” suffix will be added to part number to

designate Blu-Coat thread mask to fastener.

A NOTE ABOUT 400 SERIES FASTENERS FOR STAINLESS STEEL PANELS

In order for self-clinching fasteners to work properly, the fastener must be harder than the sheet into which it is being installed. In the case of stainless steel panels,

fasteners made from 300 Series Stainless Steel do not meet this hardness criteria. It is for this reason that 400 series fasteners are offered (Types FH4 and TP4).

However, while these 400 Series fasteners install and perform well in 300 Series stainless sheets they should not be used if the end product:

•

Will be exposed to any appreciable corrosive presence.

•

Requires non-magnetic fasteners.

•

Will be exposed to any temperatures above 300˚F (149˚C)

If any of the these are issues, please contact

for other options such as the FHP™ stud, made from precipitation hardened grade stainless

steel which is not subject to these issues.

To be sure that you are getting

genuine PEM products, look for the

PEM stamp. Studs within

the size range of the SAE

and ISO specs are also

identified with the Grade

8 and 10.9 head markings

respectively.

Thread size #10-32 does not have SAE head marking since it is technically

not within the size range of the specification.

SELF-CLINCHING STUDS AND PINS

INSTALLATION - FH™/FHS™/FHA™ THREADED STUDS

Prepare properly sized mounting hole in sheet. Do not perform any secondary operations such as deburring.

Insert stud through mounting hole (punch side) of sheet and into anvil hole.

With punch and anvil surfaces parallel, apply squeezing force to embed the head of the stud flush in the sheet. In most cases,

when using sheets .060” / 1.51 mm and thicker, the anvil requires only a straight thru hole to accommodate the stud (see

illustrations below for details). For sheets less than .060 / 1.51 mm, the hole requires a countersink with dimension A at the top to

provide for metal flow around the shank of the stud.

Tooling for sheet thicknesses less than .060 / 1.51 mm with #2 thru

SELF-CLINCHING STUDS AND PINS

INSTALLATION - FH4™/FHP™ STUDS FOR STAINLESS STEEL SHEETS

Prepare properly sized mounting hole in sheet. Do not perform any secondary operations such as deburring.

Insert stud through mounting hole (punch side) of sheet and into anvil hole.

With punch and anvil surfaces parallel, apply squeezing force to embed the head of the stud flush in the sheet.

For FH4/FHP studs, a special anvil with a raised ring is required to create a proper installation. The raised ring acts as a second displacer of the stainless

sheet material, thereby ensuring that the annular groove is filled. Please see page 6 for recommended sheet thickness range.

The special anvils are available from PEM stock or can be machined from suitable tool steel. A hardness of HRC 55 / HB 547 minimum is required to provide

long anvil life. We recommend measuring the “P” dimension every 5000 installations to ensure that the anvil remains within specification.

INSTALLATION - TFH™/TFHS™ NON-FLUSH STUDS

Prepare properly sized mounting hole in sheet. Do not perform any secondary operations such as deburring.

Insert stud through mounting hole (punch side) of sheet and into anvil hole.

With punch and anvil surfaces parallel, apply squeezing force until the punch contacts the sheet. When installed, the stud head is not

flush but will protrude approximately .025” / 0.64 mm. For sheets .030” / 0.76 mm and thicker, the anvil requires only a straight thru

hole to accommodate the stud. For sheets less than .030” / 0.76 mm down to .020” / 0.51 mm, the hole requires a countersink with

dimension A at the top to provide for metal flow around the shank of the stud. The standard punch design below provides clearance

for the stud head and reduces chances of over squeezing the head of the stud into the sheet metal.

With punch and anvil surfaces parallel, apply squeezing force on the punch sufficient only to embed the ribs on the head of the stud

Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing

proper seating of fastener as described in the installation steps. Other performance values reported are averages when all proper installation

parameters and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect performance.

Performance testing this product in your application is recommended. We will be happy to provide technical assistance and/or samples for

this purpose.

(1) Tightening torque shown is a theoretical value calculated to induce a load of 75% of minimum axial yield strength of the stud with an assumed K value or

nut factor equal to 0.20. In some applications tightening torque may needed to be adjusted based on the actual K value.

(1) Tightening torque shown is a theoretical value calculated to induce a load of 75% of minimum axial yield strength of the stud with an assumed K

value or nut factor equal to 0.20. In some applications tightening torque may needed to be adjusted based on the actual K value.

(2) Performance values shown are typical for fasteners properly installed using raised ring tooling in good condition. We recommend replacing

installation tooling when the height of the “P” falls out of tolerance (see page 18). Reductions in performance may occur as the height of the

protrusion wears. Variations in hole preparation, installation force, and sheet material type, thickness, and hardness will affect both performance and

tooling life.

(3) Performance may be reduced for studs installed into thicker sheets.

FASTENERS FOR USE WITH PC BOARDS

No matter how sophisticated or advanced, electronic components must be attached reliably and securely if they are

to deliver optimum performance. We offer several fastener products for use with PC boards to satisfy component-to-

board, board-to-board, and board-to-chassis attachment needs.

ReelFast® surface mount fasteners

mount on PC boards in the same manner and at the same time as other surface

mount components prior to the automated reflow solder process. The fasteners simply become another board

component. This alleviates concerns about potential damage to PC boards due to improper secondary installation

operations. The fasteners are provided on tape and reel compatible with existing SMT automated installation

equipment. The benefits of using ReelFast® SMT fasteners are: faster assembly; reduced scrap; reduced handling; and

reduced risk of board damage.

Broaching fasteners

can also offer practical alternatives to “loose” hardware. A broaching fastener is a knurled-shank

fastening device that can be pressed into a hole to provide a permanent, strong, threaded or unthreaded attachment

point in PC boards. They can also be used in aluminum, acrylic, casting and polycarbonate components. Specially

formed axial grooves around the shank of the fastener “broach” or cut into the material, creating a firm, interference-

type fit resistant to rotation. In PC boards, broaching fasteners are recommended for use in non-plated holes.

Broach/flare-mount standoffs

(KFB3™) offer a combined broach/flare feature for even greater pullout performance

in PC board materials.

NOTE ABOUT PLATED AND UNPLATED MOUNTING HOLES FOR BROACHING FASTENERS

Broaching and broach/flare types are designed for unplated mounting hole applications. If used in plated mounting holes, the stresses involved

can damage the plating, push out the plating entirely, or break any traces inside the board that might be connected to the plated hole. When

installing into non-plated mounting holes there may even be issues with delamination, measeling or crazing in some instances.

Increasing the mounting hole size +.005” to +.008” /+0.13 mm to +0.2 mm may relieve these conditions. If increasing the mounting hole does

not correct the issue then we recommend our surface-mount type fasteners.

It is always recommended that you try the fasteners in your specific application before full production begins. We are happy to provide samples

for this purpose.

General recommendations for “Keep Out” areas are the same as our “Min. Distance Hole C/L to Edge” dimensions stated in the dimensional

charts of our bulletin.

FASTENERS FOR USE WITH PC BOARDS

(1) PennEngineering manufactures and stocks the installation tooling for KFB3 fasteners.

KFB3™ FASTENERS

Punch or drill properly sized round mounting hole in board.

Place fastener into the anvil hole and place the mounting hole over the shank of the fastener

as shown in diagram to the left.

Using a punch flaring tool and a recessed anvil, apply squeezing force until the shoulder of

the fastener contacts the board. As the fastener seats itself in the proper position, the punch

tool will flare the extended portion of the shank outward to complete the installation. The

combination of broaching and flaring provides high pushout performance.

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing

proper seating of fastener as described in the installation steps. Other performance values reported are averages when all proper

installation parameters and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect

performance. Performance testing this product in your application is recommended. We will be happy to provide technical assistance and/

or samples for this purpose.

(2) These are typical values for parts installed in drilled mounting holes. Punched mounting holes yield values approximately 15% less.

LN-7

LK™/LKS™/LKA™ PEMFLEX® LOCKNUTS

The PEM design utilizes two rugged, semicircular flexing jaws instead of several less-supported segments. The greater ruggedness and

retention of this PEMFLEX® action prevents relaxation and loosening of the fastener in severe service. This design also protects the screw

threads. Clearances obtained by only two interruptions of a full circumference, together with the spreading of the jaws by the entering

screw, minimize the possibility of thread damage.

•

Hex shoulder provides increased pull-through performance and a positive stop during installation.

•

The flexing action of locking feature permits repeated use and effective locking torque.

•

Thread locking performance of LK and LKS fasteners (with MD finish) and LKA fasteners (lubricated) are equivalent to applicable

NASM25027 specifications.

The graph represents the clamp load of the joint versus the amount of

cycles during transverse vibration testing for an S-RT™ free-running

locknut, a standard hex nut and a hex nut with a split ring lock washer.

Testing conditions:

Transverse vibration testing.

M6 thread size nuts, average of 30 pieces.

Clamp load applied using metric property class 10.9 screws.

Nuts tested until loss of clamp load or 2,000 cycles is reached.

S-RT™ FREE-RUNNING LOCKNUTS

Free-running locking feature allows screw to turn freely until clamp load is applied. If the tightening force is removed, these nuts no

longer provide any torsional resistance to rotation.

•

Resistant to vibrational loosening.

•

Back side of panel is flush or sub-flush for screw

installation.

•

Locking feature reusability is not affected by

number of on/off cycles.

•

Uses same mounting hole and installation

tooling as standard S™ nuts.

•

Recommended for use in steel or aluminum sheets

HRB 80 / HB 150 or less.

SELF-LOCKING FASTENERS

CFN™ NUTS

Prepare properly sized mounting hole in sheet. Do not perform any

secondary operations such as deburring.

Insert fastener into the anvil hole and place the mounting hole over

the shank of the fastener (preferably the punch side) as shown in
drawing.

With installation punch and anvil surfaces parallel, apply squeezing

force until the shoulder of the fastener contacts the sheet.

INSTALLATION

FE™/FEO™/UL™ NUTS

Prepare properly sized mounting hole in sheet. Do not perform any

secondary operations such as deburring.

Insert fastener into the anvil hole and place the mounting hole

(preferably the punch side) over the shank of the fastener as shown in
the drawing.

With installation punch and anvil surfaces parallel, apply squeezing

force to the knurled collar until knurled collar is flush with top of the
sheet for sheets .060”/1.5 mm thick and up, or until shank is flush with
the bottom of the sheet for sheets .040” / 1 mm to .060”/1.5 mm thick
for FE/FEO nuts.

PEM miniature fasteners must be installed by a force applied through parallel
surfaces. Since force must not be applied to the barrel, a cavity must be used in
either the punch or anvil so that the installation force is applied to the knurled collar.
“D” dimensions for the punch or anvil cavity are given in the tables on page 5.

INSTALLATION RECOMMENDATION

In applications for sheet thicknesses between the two ranges (see “Sheet
Thickness” on page 5) use the fastener with the larger “A” dimension. For
example, if you want a #4-40 thread and your sheet thickness is between
.045”/1.14 mm and .059”/1.49 mm, you should use FE or FEX nuts. This is not
recommended installation practice, but in this case if it is necessary, you should
install the fastener so that the bottom of the shank is flush with the underside
of the sheet (instead of having the top of the knurled collar flush with the top of
the sheet). When this method is used, care must be taken to protect the fastener
against crushing which would damage the threads. This method will also result in
reduced pushout and torque-out values.

(1) Axial strength for UL, FEO, FE, PL and PLC locknuts are limited by knurled ring strength.

(2) Screw strength level shown is the minimum needed to develop full nut strength, higher strength screws may be used.

(3) Tightening torque shown will induce preload of 65% of locknut min axial strength with K or nut factor is equal to 0.20. In some applications tightening

torque may need to be adjusted based on the actual K value. If heat treated steel screw strength is less than the value shown, tightening torque

should be proportionately reduced by multiplying the torque shown by the actual screw strength over the screw strength shown. For screws of other

materials, never exceed the lower of this reduced torque or the tightening torque recommended for the screw. If higher strength screws are used,

torque is not adjusted upward because assemble strength is still limited by locknut strength.

(4) Unless otherwise noted, (see note 6) SL locknuts have axial strength exceeding the min tensile strength of 180 ksi/Property Class 12.9 screws. Contact

tech support regarding assemble strength for higher strength screws.

(5) Tightening torque shown will induce preload of 65% of locknut min axial strength with K or nut factor is equal to 0.20. In some applications tightening

torque may need to be adjusted based on the actual K value. All tightening torques shown are based on 180 ksi/ Property Class 12.9 screws. For

lower strength heat treated steel screws the tightening torque is proportionately less. For example, for 120 ksi screws (Grade 5), torque is 67% of value

shown. For 900 MPa screws (Property Class 9.8) torque value is 74% of value shown. For screws of other materials, never exceed the lower of this

reduced torque or the tightening torque recommended for the screw.

(6) Due to limited nut height in this size, failure mode is screw stripping and axial strength value shown is slightly less than min tensile strength of 180 ksi/

Property class 12.9 screw.

(7) All LK, LKS, LKA, LAC, LAS and LA4 locknuts have axial strength exceeding the min tensile strength of 180 ksi/Property Class 12.9 screws. Contact tech

support regarding assemble strength for higher strength screws.

SELF-LOCKING FASTENERS

NASM25027 AS APPLIED TO PEM® SELF-CLINCHING, SELF-LOCKING NUTS

PEM FE, FEO, LAS, LAC, LA4, LK, LKS, LKA, PL and PLC locknuts are produced to meet the prevailing locking torque

requirements of NASM25027. Specification NASM25027 is a rather lengthy spec which includes many requirements

for attributes such as tensile strength and wrenching strength which are not applicable to PEM self-clinching, self-

locking nuts. It is difficult for those not familiar with the specification to determine exactly which portions of it apply

to the locking torque of PEM self-clinching, self-locking nuts. This matter is further complicated by the fact that

many of the requirements in the specification that do apply, apply only to qualification and are not so called “quality

conformance inspections” which need to be applied to every lot of product. The fact of the matter is that only one

test (room ambient temperature locking torque per the first row of Table IV) needs to be applied on a regular basis

of PEM self-clinching, self-locking nuts. This requirement is defined by Table XIV and the permanent set test is not

required per footnote 1. The requirements for this test are given in Paragraphs 3.8.2.2.1 and 3.8.2.2.2. The test method

is specified in paragraphs 4.5.3.3. and 4.5.3.3.4.1. For convenience of those who do not have access to this specification

and/or are not familiar with specification language, these test requirements and test methods are re-stated below in

layman’s terms.

The one required test is a 15 cycle re-usability test. There are two values of torque which are required by specification.

The first is a maximum torque value which dare not be exceeded anytime during the 15 installation and removal cycles.

The second is a minimum breakaway torque which must be met during the 15th removal cycle. These torque values

are shown in Table III of specifications NASM25027. They are also listed below for PEM fastener sizes only and also

for metric sizes.

Details of the test procedure and significant definitions can be found on our web site at:

A NOTE ABOUT FASTENERS FOR STAINLESS STEEL PANELS

In order for self-clinching fasteners to work properly, the fastener must be harder than the sheet into which it is being installed. In

the case of stainless steel panels, fasteners made from 300 Series Stainless Steel do not meet this hardness criteria. It is for this

reason that 400 series fasteners are offered (Types MSO4, T4, TK4 AND TS4). However, while these 400 Series fasteners install

and perform well in 300 Series stainless sheets they should not be used if the end product:

•

Will be exposed to any appreciable corrosive presence.

•

Requires non-magnetic fasteners.

•

Will be exposed to any temperatures above 300˚F (149˚C)

If any of the these are issues, please contact

for other options.

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing

proper seating of fastener as described in the installation steps. Other performance values reported are averages when all proper

installation parameters and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect

performance. Performance testing this product in your application is recommended. We will be happy to provide technical assistance and/

or samples for this purpose.

(2) Performance in torque-out and pull-thru will depend on the strength and type of screw being used. In most cases the failure will be in the screw and

not in the self clinching standoff. Please contact our Applications Engineering group with any questions.

PEM® PF11™/PF12™ CAPTIVE PANEL SCREWS

PEM® PF11/PF12 panel fasteners provide design flexibility by offering three styles of installation types, each having the same profile

or look above the sheet or panel into which it is installed. The various mounting types include self-clinching, flare-mounted, and

floating styles. Each offers a distinct advantage depending on your application. The standard selection of knobs include knurled

or smooth metal caps and plastic PEM C.A.P.S.® (colored access panel screws).

•

Installs flush on back side of panel.

•

Available in three screw

lengths.

Self-clinching

Flare-mounted, Floating

•

Compensates for mating hole misalignment.

•

Installs into any panel hardness.

Key features include:

Universal Phillips/slot drive (except for plastic cap).

Shoulder on retainer to provide positive stop during installation.

Anti cross-threading feature (designated with an “M” in the

part number). Eases assembly, aligns components, improves

assembly line productivity, prevents jamming, and slides

through clogged internal threads.

A NOTE ABOUT FASTENERS FOR STAINLESS STEEL PANELS

In order for self-clinching fasteners to work properly, the fastener must be harder than the sheet into which it is being installed. In the case of stainless steel panels,

fasteners made from 300 Series Stainless Steel do not meet this hardness criteria. It is for this reason that 400 series fasteners are offered (PFC4). However, while

these 400 Series fasteners install and perform well in 300 Series stainless sheets they should not be used if the end product:

•

Will be exposed to any appreciable corrosive presence.

•

Requires non-magnetic fasteners.

•

Will be exposed to any temperatures above 300˚F (149˚C)

If any of the these are issues, please contact

for other options.

HSCB™ SELF-CAPTIVATING SCREW

NOTE:

HSCB screws, HSR nuts and HSL springs are sold separately.

(1) As with all Class 2A/6g external threads with an additive finish, the maximum major and pitch, after plating, may equal basic sizes and be gauged to

Class 3A/4h, per ANSI B1.1, Section 8, Table 3A and ANSI B1.13M, Section 8, Paragraph 8.2.

(2) See PEM Technical Support section of our website (

) for related plating standards and specifications.

(3) HRB - Hardness Rockwell “B” Scale. HB - Hardness Brinell.

To select proper length code of nut/standoff:

Determine “G”, the distance from the top surface of the heat sink to

the top of the P.C. Board.

Find the combination of Screw (HSCB) and Nut (HSR) whose sum of

Screw Factor (SF) plus Nut Factor (NF) are closest to G.

Find D = G – SF – NF. The D value must be a negative number

between zero and 1mm or 1/32” (1 dash length of HSR nut).

The actual working load is equal to the Spring (HSL) Working Load

+ (D x spring rate k). Lower D value results in lower force.

The new HSCB™ engineered mounting system provides secure attachment of a heat sink to the circuit board while providing firm

contact to the chip component allowing optimum heat dissipation. The three-piece fastening system, sold individually, includes the

screw, spring and receptacle nut. The clamp load created is determined

by the spring rate and the amount of deflection that is designed into

the joint of the hardware. The system also allows for slight expansion

and contraction of the joint components without stress to the delicate

circuitry. The unique “click” feature lets the user know when the

fastener is completely installed.

HSL™ SPRINGS

HSL springs are engineered to provide a reliable and repeatable spring rate when

assembled with mating PEM hardware. The spring rate is critical to the successful

assembly of your heat sink. Clamp load will be determined by the spring rate and

deflection that is designed into the joint.

SCB™/SCBJ™ FASTENERS

Prepare properly sized mounting hole in sheet.

Place the fastener through mounting hole and into anvil. A flat or

recessed punch can be used.

With installation punch and anvil surfaces parallel, apply squeezing

force to the top of the screw head and the underside of the sheet

material. The squeezing action forces the shoulder of the screw

into the sheet, displacing sheet material, causing it to fill the void

under the head and shoulder of the screw.

SCBR™ FASTENERS

Prepare properly sized mounting hole in sheet.

Do not perform any

secondary operations such as deburring. If the hole is punched, be

sure to install fastener into punched side of hole.

Assemble spring on screw by rotating spring counter clockwise

and position assembly into recessed magnetic punch.

Position hole in workpiece over retractable anvil pin.

With installation punch and anvil surfaces parallel, apply squeezing

force on top of the screw head and the underside of the sheet

material. The squeezing action forces the displacer of the screw

into the sheet, causing it to reduce the mounting hole diameter and

captivate the screw.

HSCB™ FASTENER INTO HEAT SINK

Prepare properly sized mounting hole in heat sink. Do not perform any

secondary operations such as deburring. If the hole is punched, be sure to

install the fastener into the punch side of the hole.

Place the head of the screw into the recess of the installation anvil

and position assembly into recessed magnetic punch.

Place the spring over the shoulder of the screw, maintaining concentricity.

Position the heat sink mounting hole over the screw.

Bring the heat sink down over the screw and onto the shoulder of the screw.

With installation punch and anvil surfaces parallel, apply a squeezing force

to the heat sink and the head of the screw. The squeezing action forces the

displacer of the screw into the heat sink, causing it to reduce the mounting

hole diameter and captivate the screw and spring.

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing

proper seating of fastener as described in the installation steps. Other performance values reported are averages when all proper installation

parameters and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect performance.

Performance testing this product in your application is recommended. We will be happy to provide technical assistance and/or samples for

this purpose.

(2) With lead-free paste. Average values of 30 test points. The data presented here is for general comparison purposes only. Actual performance is

dependent upon application variables. We will be happy to provide samples for you to install. If required, we can also test your installed hardware and

provide you with the performance data specific to your application.

(3) Torque values shown will produce a preload of 70% minimum tensile with a nut factor “k” equal to .1.

(4) Failure occurred at the solder joint. Screw retention strength is greater than the retainer.

PEM® R’ANGLE® fasteners provide strong right angle attachment points in sheet metal or P.C. boards.

RAA™

and

RAS™

fasteners for metal are simply pressed into a rectangular mounting hole of the proper size.

SMTRA™

fasteners are installed

onto P.C. boards using standard surface mount techniques. The holding power of the fastener is unaffected by the repeated

tightening and loosening of the screw.

PEM® R’ANGLE® fasteners are cost-effective replacements for:

•

Bent edge tabs

•

Bent center tabs

•

Bent flanges

•

Angle brackets

•

Tack welds

•

Loose hardware

PEM® R’ANGLE® fasteners provide many advantages over bent tabs and flanges, including:

•

More predictable designs

•

Material savings

•

Tighter design control

•

Improved shielding characteristics

•

Reduction of loose hardware

•

Fewer assembly steps

•

Unmarred panel surfaces

(2) HRB - Hardness Rockwell “B” Scale. HB - Hardness Brinell.

(3) Optimal solderability life noted on packaging.

The mounting hole is defined by two dimensions. The two thick lines

shown must be straight for the entire length defined by “Side 2” and

must be separated by the distance shown as “Side 1” (Side 1 and Side 2

are the two dimensions given for the mounting hole on pages 3 and 4).

The illustration shows three examples (#1, #2, and #3) of how it can be

achieved. Example #4 in the lower right side will not work.

INSTALLATION

Step 1.

Prepare properly sized mounting hole in both panels. Do not perform any secondary

operations such as deburring. If the hole is punched, be sure to install fastener into
punched side of hole.

Step 2.

Place Panel 2 with smaller mounting hole on anvil and align Panel 1 mounting hole

with the mounting hole of Panel 2. Place the smaller diameter end of the fastener
through the mounting holes as shown in the drawing to the right. (See figure SF-1).

Step 3.

With the punch and anvil surfaces parallel, apply squeezing force until the fastener

is flush with the top of Panel 1. (See figure SF-1).

NOTE:

To use Type SF or SFP as a flush-mounted

pivot point, for best results, install SpotFast

fastener into Panel 1 first, then place Panel 2

over fastener and squeeze again.

perform any secondary operations such as deburring. If the hole
is punched, be sure to install fastener into punched side of hole.

Step 2.

Using only Panel 1, with the punch and anvil surfaces parallel,
apply squeezing force until the fastener is flush with the top of
Panel 1. (See figure SFW-1).

Step 3.

To ensure proper function of washer, place washer over installed

fastener (concave side facing up), then place Panel 2 over
fastener. Apply squeezing force. Keep gap between Panel 2 and
anvil. (See “G” in figure SFW-2).

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing proper

seating of fastener as described in the installation steps. Other performance values reported are averages when all proper installation parameters
and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect performance. Performance
testing this product in your application is recommended. We will be happy to provide technical assistance and/or samples for this purpose.

(2) .040” / 1 mm test sheet material thickness was used for the -2 and -4 SKC standoffs due to the short length of the parts.

PEM® self-clinching standoffs, which use the proven self-clinching design, provide

ideal solutions for applications where mounting, spacing or stacking of panels,

boards or components are required. Pressed into round holes, these fasteners

mount permanently into metal sheets as thin as .025”/0.63mm.

Specially designed Types SO4, BSO4 and TSO4 standoffs are made from hardened

stainless steel and are ideal for clinching into stainless steel sheets. An optional nickel

plating is now available if product is expected to be used in a corrosive environment.

For more information on the proper use of PEM self-clinching standoffs, check our

web site for Tech Sheet PEM® - REF/Standoff Basics.

A NOTE ABOUT FASTENERS FOR STAINLESS STEEL PANELS

In order for self-clinching fasteners to work properly, the fastener must be harder than the sheet into which it is being installed. In

the case of stainless steel panels, fasteners made from 300 Series Stainless Steel do not meet this hardness criteria. It is for this

reason that 400 series fasteners are offered (Types SO4, BSO4, and TSO4). However, while these 400 Series fasteners install and

perform well in 300 Series stainless sheets they should not be used if the end product:

•

Will be exposed to any appreciable corrosive environment (unless finished with optional nickel plating).

•

Requires non-magnetic fasteners.

•

Will be exposed to any temperatures above 300˚F (149˚C)

If any of the these are issues, please contact

for other options.

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing

proper seating of fastener as described in the installation steps. Other performance values reported are averages when all proper

installation parameters and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect

performance. Performance testing this product in your application is recommended. We will be happy to provide technical assistance and/

or samples for this purpose.

(2) Joint failure in torque-out and pull-thru will depend on the strength and type of screw being used. In some cases the failure will be in the screw and

not in the self-clinching standoff. Please contact our Applications Engineering group with any questions.

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing

proper seating of fastener as described in the installation steps. Other performance values reported are averages when all proper

installation parameters and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect

performance. Performance testing this product in your application is recommended. We will be happy to provide technical assistance and/

or samples for this purpose.

(2) Joint failure in torque-out and pull-thru will depend on the strength and type of screw being used. In some cases the failure will be in the screw and

not in the self-clinching standoff. Please contact our Applications Engineering group with any questions.

One of the very basics of self-clinching is that the fastener must always be harder than the host sheet to ensure proper and

permanent installation. This is particularly challenging when installing fasteners into stainless steel sheets. Therefore we

have developed this line of specially hardened stainless steel fasteners for installation into stainless steel.

Refer to “Dos

and Don’ts” on page 24 for further information.

Fasteners made from precipitation hardened grade stainless including A286 stainless are particularly useful in applications

such as outdoor equipment, medical devices and chemical and food processing equipment or anywhere corrosive element

exposure is possible.

FASTENERS FOR USE IN STAINLESS STEEL SHEETS

MATERIAL AND FINISH SPECIFICATIONS

A NOTE ABOUT FASTENERS FOR STAINLESS STEEL PANELS

In order for self-clinching fasteners to work properly, the fastener must be harder than the sheet into which it is being installed. In

the case of stainless steel panels, fasteners made from 300 Series Stainless Steel do not meet this hardness criteria. It is for this

reason that 400 series fasteners are offered (Types A4, LA4, F4, SO4, BSO4, TSO4, FH4, TP4, and PFC4). However, while these 400

Series fasteners install and perform well in 300 Series stainless sheets they should not be used if the end product:

•

Will be exposed to any appreciable corrosive presence.

•

Requires non-magnetic fasteners.

•

Will be exposed to any temperatures above 300˚F (149˚C)

If any of the these are issues, please contact

http://www.pemnet.com/SGPC_Panel_Designs.pdf

for other options.

INSTALLATION

TYPES SP/SMPP

(1)

Prepare properly sized mounting hole in sheet. Do not perform any secondary operations such as deburring.

Place fastener into the recommended counterbore anvil hole and place the mounting hole over the shank of the fastener as shown

in diagram.

With installation punch and anvil surfaces parallel, apply squeezing force until the head of the nut comes into contact with the sheet

material.

RECOMMENDED

COUNTERBORE ANVIL

(1) For best results, we recommend using the installation punch and anvil shown. Deviations from recommended installation tooling may result in sheet

distortion and reduced performance.

NOTE:

Variations in hole preparation, installation tooling, installation force, and sheet material type, thickness, and hardness will affect both performance

and tooling life.

TYPES FH4/FHP

Prepare properly sized mounting hole in sheet. Do not perform any secondary operations such as deburring.

Insert stud through mounting hole (punch side) of sheet and into anvil hole.

With punch and anvil surfaces parallel, apply squeezing force to embed the head of the stud flush in the sheet.

For Type FH4/FHP studs, a special anvil with a raised ring is required to create a proper installation. The raised ring acts as a second displacer of the

stainless sheet material, thereby ensuring that the annular groove is filled. Please see page 10 for recommended sheet thickness range.

The special anvils are available from PEM stock or can be machined from suitable tool steel. A hardness of HRC 55 / HB 547 minimum is required to provide

long anvil life. We recommend measuring the “P” dimension every 5000 installations to ensure that the anvil remains within specification.

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing

proper seating of fastener as described in the installation steps. Other performance values reported are averages when all proper installation

parameters and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect performance.

Performance testing this product in your application is recommended. We will be happy to provide technical assistance and/or samples for

this purpose.

(2) Head size is adequate to ensure failure in threaded area when tested with industry standard tensile bushing diameter.

(3) Tightening torque shown will induce preload of 70% of nut min axial strength with K or nut factor is equal to 0.20. In some applications tightening torque

may need to be adjusted based on the actual K value. All tightening torques shown are based on 180 ksi/ Property Class 12.9 screws. For lower strength

screws the tightening torque is proportionately less. For example, for 120 ksi screws, torque is 67% value shown. For 900 MPa screws (Property Class

9.8) torque value is 74% of value shown.

(4) Installation controlled by proper cavity depth in punch.

TYPE TSO4

(1) Failure occurs in screw stripping using a 60 ksi screw and the shortest shank length fastener.

(2) Torque values shown will produce a preload of 70% of axial tensile strength with nut factor “k” equal to .2. Threads may strip or head of the nut may

bend and/or fail if screw is over-torqued beyond these values or if actual k value is less than .2.

(3) Joint failure in torque-out and pull-thru will depend on the strength and type of screw being used. In some cases the failure will be in the screw and not

in the self-clinching standoff. Please contact our Applications Engineering group with any questions.

(4) Performance may be reduced for studs installed into thicker sheets.

See our website for the most current version of this bulletin.

Regulatory compliance information is available in Technical

OTHER FASTENERS FOR CONSIDERATION TO USE IN STAINLESS STEEL SHEETS

Type PF11MW™

Type PF11MF™

Floating captive panel screw with unique flare-

mount feature allows fastener to “float” in mounting

hole and compensate for mating thread alignment.

(See PEM® Bulletin PF)

Type WN/WNS

Type MPP™

Self-clinching microPEM® pins that can be installed

into stainless steel sheets as thin as .02”/0.5mm.

(See PEM® Bulletin MPF)

Type MSO4™

Self-clinching microPEM® standoffs that can be

installed into stainless steel sheets as thin as

.016”/0.4mm.

(See PEM® Bulletin MPF)

ATLAS® BLIND THREADED INSERTS

Attach to panels of any hardness and provide

strong and reusable permanent threads in sheet

materials where only one side is accessible.

(See ATLAS® Catalog)

Flare-mounted captive panel screw that installs

into any panel material and is flush on back side

of panel.

(See PEM® Bulletin PF)

Designed to overcome many problems such as

burn-outs, complicated electrodes and pilots,

indexing and re-tapping to remove weld spatter.

(See PEM® Bulletin WN)

Type T4™

microPEM® TackPin® fasteners enable sheet-

to-sheet attachment in stainless steel sheets in

applications where disassembly is not required.

(See PEM® Bulletin MPF)

“Dos”

select the proper fastener material to meet corrosion requirements.

make certain that panel material is in the annealed condition.

make certain that hole punch is kept sharp to minimize work hardening around hole.

provide mounting hole of specified size for each fastener.

maintain the hole punch diameter to no greater than +.001”/.025 mm over the minimum recommended mounting hole.

make certain that fastener is properly positioned within hole before applying installation force.

make certain that fastener is not installed adjacent to bends or other highly cold-worked areas.

apply squeezing force between parallel surfaces.

utilize recommended installation tooling when installing fasteners.

install fastener in punched side of hole.

apply sufficient force to totally embed clinching ring (where applicable) around entire circumference and to bring shoulder squarely in contact with sheet. For all other fasteners, installation

will be complete when the head is flush with the panel surface.

“Don’ts”

DON’T

attempt to install a 300 series stainless steel fastener into a stainless steel sheet.

DON’T

deburr mounting holes on either side of sheet before installing fasteners – deburring will remove metal required for clinching fastener into sheet.

DON’T

install fastener closer to edge of sheet than minimum edge distance – unless a special fixture is used to restrict bulging of sheet edge.

DON’T

install fastener near bends or other highly cold worked areas where sheet hardness may be greater than the limit for the fastener.

DON’T

over-squeeze. It will crush the head, distort threads, and buckle the sheet. Be certain to determine optimum installation force by test prior to production runs.

DON’T

attempt to insert fastener with a hammer blow – under any circumstances. A hammer blow won’t permit the sheet metal to flow and develop an interlock with the fastener’s contour.

DON’T

install screw in the head side of fastener. Install from opposite side so that the fastener load is toward sheet. The clinching force is designed only to hold the fastener during handling and

to resist torque during assembly.

SELF-LOCATING PROJECTION WELD NUTS

NIF

INSTALLATION

With a PEM® weld nut inserted in the properly sized hole (see above), bring the electrode force up sufficiently to clamp the projections of

the fastener firmly against the sheet without embedding any portion of the projections. Be sure the electrodes are centered, and that the

electrode faces are flat so that the force is applied evenly to all three projections.

Set the current or heat regulator on the low side and adjust along with the weld time until a good weld is produced. For mild steel, which

has a medium electrical resistance, there is a wide range of adjustments possible. For austenitic stainless steel, which has a high electrical

resistance, the range is narrow at low heat.

Adjust squeeze time so that there is adequate time for the electrodes to close and develop proper forces (suggested initial setting 35

cycles). The weld period should be established by starting with the settings suggested in the tables on page 4. As indicated above for

current adjustments, a wide range of time is possible with mild steel, but there is a limited range with stainless steel. If weld time starts too

soon, and proper welding is not achieved, the squeeze time should be lengthened. Also, the electrodes should be moved closer together

so that they require less travel time to close on the work. Longer squeeze times will have no effect on the quality of the weld. However,

they do affect productivity and decrease the number of weld nuts that can be installed per hour. Hold time is set long enough to permit

cooling and solidification of the weld before removing the electrodes. Start with 15 cycles and lengthen if necessary.

PERFORMANCE DATA

GUIDES TO BETTER WELDING

Electrodes, weld nuts, and panels must be clean and free of grease, rust, and metal burrs. When welds appear satisfactory on installed nut, but pushout

values are low, one or more of the following may be the cause:

Ram pressure too high.

Current too low.

Panel not clean.

Weld nuts not centered under electrodes.

Hold time not long enough to allow proper cooling.

Pressure regulator on welding equipment drifts.

If installed threads are distorted, the following singly or in combination may be the cause:

Weld time too long.

Current too high.

Ram pressure too high.

Should it be impossible to produce a proper weld because weld time starts before electrodes close on the work, shorten the gap between the electrodes

so that they take less time to move into position and/or lengthen the squeeze time.

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by observing proper

seating of fastener as described in the installation steps. Other performance values reported are averages when all proper installation parameters

and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure may affect performance. Performance

testing this product in your application is recommended. We will be happy to provide technical assistance and/or samples for this purpose.

(A) Electrode Force is the force exerted by the electrodes on the fastener and sheet to clamp them together and ensure good electrical contact. Electrode force also

sets the weld nut down flush on the sheet as the projections melt during the welding period. Insufficient electrode force may result in flashing, spitting, burning,

spatter, and discoloration. On the other hand, excessive electrode force may flatten the fastener projections before proper welding temperature is reached or may

embed the projections of the cold fastener into the sheet. Excessive electrode force can also distort threads during the weld cycle.

(B) Secondary Current determines the heat applied to the PEM® weld nut and sheet. Heat is in direct proportion to weld time, resistances of the materials, and the

square of the current. Current should not be set so high as to cause flashing or spattering or excessive heat which will distort the threads. Low currents may produce

good looking welds but pushout and torque-out strengths will not be satisfactory.

(C) Timing Cycle for projection welding comprises four periods. 1) the squeeze time in which the electrodes move into position and develop the required force; 2) the

weld time when the current is applied; 3) the hold time while the weld congeals and cools; and (4) the off time for positioning the work for the next weld nut.

NOTE: The setting guides shown in the above charts are for reference only and may differ for your welding equipment.

SI® inserts are typically specified in applications where strong, durable metal threads are required in plastic material,

especially where frequent assembly and disassembly of the unit for service or repair is necessary.

•

Applications for SI® products include: electronics (including wearables, smart phones and hand held devices),

automotive, aerospace and defense, medical, transportation, industrial and recreational equipment.

•

SI® inserts are available in brass, stainless steel and aluminum.

•

SI® inserts are available in a large variety of ultrasonic / heat staking, molded-in or press-in types.

•

Aluminum and stainless steel inserts for plastics offer lead-free alternatives to leaded brass typically used for brass

inserts.

–

Lead-free inserts offer alternative to leaded brass to address environmental and end-of-life recycling concerns.

–

NEW aluminum inserts

are approximately 70% lighter than brass equivalents and made from lead-free aluminum.

–

Stainless steel inserts are typically stronger than brass and may offer better protection from certain types of

corrosive agents.

•

SI® microPEM® inserts provide threads as small as M1.

SI® INSERTS FOR PLASTICS

ULTRASONIC / HEAT STAKING INSERTS

•

Ultrasonic - Installed by pressing the insert into the mounting hole with

ultrasonic insertion equipment while simultaneously applying a high

frequency vibration. Frictional heat caused by the vibration melts the plastic

surrounding the insert allowing easy insertion. When the vibration ceases, the

plastic solidifies, locking the insert permanently in place.

•

Heat Staking - Installed by pressing the insert into the mounting hole with a

thermal press to melt the plastic surrounding the insert.

MOLDED-IN INSERTS

•

Installed during the molding process, the inserts are located in the mold

cavity by core pins. When the mold opens, the core pins are withdrawn

leaving the inserts permanently encapsulated in the plastic section with only

the threads exposed.

•

Installing the inserts during the molding process eliminates the need for

secondary steps or installation equipment.

(1) The values reported are averages for ultrasonically inserted inserts when

all installation specifications and procedures are followed. Variations

in mounting hole size, sheet material and installation procedure will

affect results. Performance testing of this product in your application is

recommended. Samples can be provided for this purpose

(2) Torque-out performance will depend on the strength and type of screw

being used. In most cases, the screw threads will fail before the insert

threads. For testing purposes, inserts were installed using heat stake

equipment into a flat sheet.
