🔹 Product Overview

A Cotter Pin, also known as a Split Pin, is a metal fastener consisting of a folded wire with two tines that are bent during installation to lock components securely in place.

The pin is inserted through a pre-drilled hole in a shaft, bolt, or clevis pin, and the legs are spread apart to prevent accidental removal. Cotter Pins are reusable in temporary applications and provide excellent safety locking in rotating or moving assemblies.
