Cotter Pin

Cotter Pin is a simple yet essential mechanical component, also called a split pin, typically made of metal in a "U" or "L" shape. It is used to secure bolts, pins, or other parts, preventing them from loosening or disengaging due to vibration or movement. Known for its simplicity, low cost, and high reliability, the Cotter Pin is widely used in automotive, agricultural machinery, and industrial equipment, making it a critical safety fastener in mechanical assemblies.
