These fasteners provide positive locking in quick change applications where there is frequent insertion and removal. They allow for consistent fastening force, eliminating the chance for under or over tightening by the operator. The fastener is mounted to the fixture and the receptacle (sold separately) is mounted to the base. The spring in the fastener allows for a range of fixture thicknesses. Turning the knob or lever (supplied by user on this knobless version) one quarter turn aligns and locks the fastener into place. The fasteners are marked with “ON” and “OFF” indicators to show the position of the fastening pins.

The bodies are 303 stainless steel with an electroless nickel plating finish. Pins made from quenched and tempered stainless steel. Shank made from SKS3 steel with an electroless nickel plating finish, heat treated. Three stainless steel socket head cap screws for mounting are included (M3X0.5 - 6 mm long). Receptacles are available (order separately).
