Cotter Pins

(6 Products)

Cotter pins are small, essential fasteners used in a wide range of applications to secure components and prevent them from unintentional disassembly. Typically made of durable materials such as stainless steel, brass, or zinc-plated steel, cotter pins consist of a cylindrical body with a split end and two tines that can be bent outward after insertion. This design allows them to slide through holes in various mechanical parts, like bolts or axles, and then lock in place by spreading the tines, ensuring a secure connection.
