A spring pin is a mechanical fastener that holds two or more parts of a machine relative to each other. The main diameter of the spring pin is larger than the diameter of the hole, and there are chamfers at one or both ends so as to start the pin into the hole. The spring action of the pin allows it to compress when presenting the diameter of the hole. The force exerted by the pin on the hole wall keeps it in the hole, so the spring pin is considered as a self-retaining fastener.
