These positive locking quick release pins have a wide range of uses in fastening, locating, and alignment applications. The pins will not release until the button on the handle is depressed. Once the button is depressed, the balls retract into the shank allowing the pin to be inserted or removed into or out of a hole. The shanks are made from 17-4 stainless steel. The dome actuators and handles are made from 303 stainless steel. The large ergonomic dome actuator button facilitates easy installation and removal. Pins in other grip lengths are available as special orders.
