These ball lock clamping pins are designed to be used 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. These clamping pins are used with the receptacles (standard or safety lock style) referenced on the table. The standard style allows the pin to be inserted or removed in one operation, and the safety lock style allows the balls to be locked in place preventing accidental release. They can be used with locating pins to provide highly accurate positioning. The ball lock clamping pins are made from hardened 1045 carbon steel with an electroless nickel plating finish.
