DZUS turnlock fasteners—named after their inventor—William Dzus (pronounced “Zeus”) refers to a type of proprietary quarter-turn lock fastener that is often used to secure skin panels on aircraft and other high-performance vehicles. Turnlock fasteners are also referred to as quick-action panel fasteners.[2]
Dzus fasteners are also used to secure plates, doors, and panels that require frequent removal for inspection and servicing. These fasteners are notable in that they are of an “over-centre” design, requiring positive sustained torque to unfasten. Thus, any minor disturbance to the fastener (e.g. vibration) will tend to correct itself rather than proceed to further loosening as it would in threaded fasteners. Turnlock fasteners are available in several different styles and are usually referred to by the manufacturer’s trade name. Some of the most common are DZUS, Camloc, and Airloc.
We offer a wide range of fastener options that can be used for both on and off road applications. We offer several Dzus fastener plates, Dzus springs, Dzus buttons, and 1/8″ Aluminum pop rivets. Our precision fasteners make it easy to build with professional results.
