Stainless steel quick-release pin QCBUS series

with button

Product Description
These quick-release one-touch fasteners provide positive ball-locking in applications requiring frequent insertion and removal. The pins are designed for use with the matching ball-locking receptacles. The pin is threaded into the fixture while the receptacle is mounted to the base. On insertion the balls expand to lock the fixture; pressing the handle button retracts the balls to allow removal without tools. Tapered pin end facilitates alignment. Compatible with locating pins for precise positioning. Bodies in 303 stainless steel (natural finish); button in 420 stainless steel; balls in hardened 440C stainless steel. Receptacles and lock nuts sold separately.
