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 receptacles are used with the clamping pin QCBA0816-M5. As the pin is inserted into the receptacle, the three balls secure the clamping pin in place. The standard style allows the pin to be inserted or removed in one operation. They can be used with locating pins to provide highly accurate positioning. The body is made from 1045 carbon steel with an electroless nickel plating finish. Ordered separately, stainless steel nuts for fastening the receptacles are referenced on the table.
