R Pin

An R pin, also called a snap pin, is a wire pin with a loop at one end and a bent leg that snaps over a shaft. It holds parts in place and can be removed by hand.

An R pin, also called a snap pin, holds a clevis pin or similar part in place. It is inserted through a hole and the spring legs keep it from falling out. It can be removed and reused by squeezing the legs together.

This kind of pin is often made in spring steel or stainless steel. Spring steel gives the pin its snap action, while stainless steel offers corrosion resistance.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance. On receipt, check the wire diameter, the loop shape and that the legs snap back into place.
