Cotter Pin

A Split Pin or Cotter pin (commonly known as a split pin in the U.S. and parts of British English) is a metal fastener made from a single length of wire folded in half to form a U-shape with a looped or rounded head (the eye.)

How It Works

• Insertion: The two prongs (legs) are inserted through a pre-drilled transverse hole in a bolt, axle, shaft, or clevis pin.
• Locking: Once pushed through, the legs are bent apart (typically outward and around the fastener) to prevent the pin from backing out.
• Retention: It acts as a mechanical stop to keep components like castellated nuts from vibrating loose.

Common Types of Cotter Pins

• Split Cotter Pin: The traditional two-prong wire pin where the legs are manually bent apart after installation.
• Hairpin Cotter Pin (R-Clip): Shaped like the letter "R," this spring-steel clip snaps into place around a shaft or pin for fast removal and reusability.
• Self-Locking Cotter Pins: Variations like bow-tie or Rue Ring pins feature built-in latching mechanisms that lock without needing the prongs bent by hand.
• Common Applications

• Automotive & Machinery: Securing wheel bearings, axle nuts, and linkage pins.
• Bicycles & Engines: Holding pedal cranks or mechanical rods in alignment.
• Hardware & Towing: Locking hitch pins on trailers, farm equipment, and lawn mowers.
