Quick-Locking Pin

The Slic Pin (for Self-Locking Implanted Cotter) secures and self-locks through an implanted plunger (locking detent) that functions as a self-contained cotter pin.

The Slic Pin (for Self-Locking Implanted Cotter) secures and self-locks through an implanted plunger (locking detent) that functions as a self-contained cotter pin. The pin's solid, spring-loaded "wedge-shaped plunger" easily and automatically retracts when the pin is inserted into a hole. The wedge's angled, ramplike face permits smooth insertion. Once inserted, the plunger springs back up, locking the pin into the application. A vertical face at the back of the plunger prevents the pin from backing out. The semipermanent quicklocking pin is an alternative to a clevis pin and cotter pin; a pin and retaining ring; or a nut and bolt.
