Self Locking Implanted Cotter Pin from Pivot Point

Hustisford, WI – Pivot Point Incorporated has invented a new quick locking pin named the SLIC Pin™ (U.S. patent number 6,872,039, foreign patents pending). The pin functions as a pin and cotter all in one.


SLIC is an acronym for Self Locking Implanted Cotter, and as the name implies, the pin is secure and self locking through the use of an implanted plunger (locking detent) that effectively functions as a self-contained cotter pin. The pin features a solid, spring loaded “wedge shaped plunger” that combines ease of use with secure fastening. The wedge shaped plunger easily and automatically retracts when the pin is inserted into a hole. The angled, ramp-like face of the wedge ensures smooth insertion. Once fully inserted, the plunger springs back up, locking the pin into the application. The vertical face at the rear of the plunger prevents the pin from backing out.

The SLIC™ Pin is intended for use as a semi-permanent quick locking pin and can be used in a multitude of applications. It replaces other labor intensive fastening combinations such as a clevis pin & cotter pin, a pin and retaining ring or a nut and bolt. It is used in the same manner as the aforementinoed, but has much improved functionality and ease of assembly. The plunger is as strong as a respective cotter pin. The simple, one-piece design means easier, safer and faster assembly speeds. No tools are needed, there are no sharp ends as with cotter pins and there are less items to purchase and inventory.

The SLIC Pin™ is especially beneficial in applications with blind holes and/or space constraints. The SLIC Pin™ is quickly and easily inserted from just one side. Unlike other tedious fastening methods, there is no need to access the other side to secure another fastener such as a cotter pin, a nut or a clip.
