This spring pin (also called tension pin) is a slotted, hollow cylindrical mechanical fastener that secures the position of two or more parts typically in machinery. Their body diameter is larger than the hole diameter. and the spring action of the pin allows it to compress as it assumes the diameter of the hole. This force allows the pin to remain in the hole making it a self locking fastener. Slot on the side make it easier to insert the pin into a hole and compress.
