Cotter Pin

Cotter pins are split pins that are opened outward after passing through a hole. The most common type is the extended cotter pin, which has one end that is slightly longer than the other. Often, cotter pins are used in conjunction with clevis pins. Cotter pins are also referred to as split pins.
