Spring pins, sometimes referred to as slotted pins, rolled pins or coiled rolled pins, are hollow, cylindrical tube-style press fit fasteners with chamfered ends.The spring action of the pin allows it to compress as it assumes the diameter of the hole. The force exerted by the pin against the hole wall retains it in the hole, therefore a spring pin is considered a self retaining fastener.
