Positive locking in quick change applications where there is frequent insertion and removal of a fastener. They allow for consistent fastening force, eliminating the chance for under or over tightening by the operator. They are designed to be used with the cam receptacle referenced on the table. The fastener is mounted to the fixture and the receptacle is mounted to the base. The spring in the fastener allow for a range of fixture thicknesses.
