These specialty turnlock fasteners feature an “over-center” design that requires positive sustained torque to unfasten — any minor vibration will tend to self-correct rather than loosen. Also known as TurnLoc, Camloc, Airloc, and Southco Dzus fasteners.

Pro-Werks Dzus buttons are available in aluminum or steel, in flat head or dome head styles, and in several grip lengths to match your panel thickness. Shank diameter: 0.406", head diameter: 0.700". Sold in packs of 10.

What Are Quarter-Turn Dzus Fasteners?

The Dzus fastener — also known as a turnlock fastener or quick-action panel fastener — is a quarter-turn spiral cam lock fastener originally developed for securing skin panels on aircraft. The unique “over-center” design requires positive sustained torque to unfasten, meaning any vibration disturbance will tend to self-correct rather than loosen the fastener. Common trade names include Dzus, Southco Dzus, Camloc, and Airloc.
