Split Cotter Pins - Metric - Stainless Steel


A Split Cotter Pin is a simple fastening device to prevent parts being released off the end of a shaft. Alternatively, they can be very useful to prevent nuts coming undone off a threaded fastener by simply drilling through nut and bolt. The o/d of the pin is made marginally smaller than the hole size to give easy fit. Once inserted the legs are bent over in opposite directions to complete the fastening.
