The magnetic locking pin is designed to be used with the receptacle series QCMA, specifically the QCMA0612A. It is designed for light duty holding in quick change applications where there is frequent insertion and removal of a fastener. As the pin is inserted into the receptacle, the magnet in the receptacle holds the pin in place. They can be used with locating pins to provide highly accurate positioning. The pin is threaded into the fixture. The pins are made from 1045 carbon steel with an electroless nickel plate finish.
