Cotter Pins & Split Pins

Cotter pins, also known as split pins and cotter keys, are a steel formed pin inserted into a drilled hole of a clevis pin, shaft, or other mating assembly. The pin has a split end that is separated to secure the part after insertion. Inserting cotter pins is a simple process, as they can be installed quickly and with no special tools. Most cotter pins are able to be easily removed and reused, saving time and money. G.L.
