Quick-release fastener with ball bearing QCBU0608-10

These quick release fasteners provide positive locking in quick change applications where there is frequent insertion and removal of a fastener. They are designed to be used with ball-locking receptacle series QCBU-M. Lock nuts are available under series RBN. The pin can be threaded into the fixture and the receptacle is mounted to the base. As the pin is inserted into the receptacle, the balls on the pin expand and lock the fixture in place. The pin will not release until the button on the handle is depressed, allowing the balls to retract into the shank so that the pin can be inserted or removed from the receptacle without the use of tools. The end of the pin is tapered to make alignment of the pin easy. They can be used with locating pins to provide highly accurate positioning. The body and button are made from 1045 carbon steel with an electroless nickel plate finish. The balls are made from hardened 440C stainless steel. Spring and snap ring are made from 304 stainless steel. The O-ring is made from FKM rubber. Quick Changeover, perfect for a variety of applications!
