Value Collection P20137 Hammerlock Cotter Pin 0.25x3 in

Product Description

The VALUE COLLECTION P20137 is a hammerlock cotter pin used to secure clevis pins, shaft ends, and linkage assemblies in mechanical and industrial applications. Constructed from Grade 2 steel with a zinc-plated finish, this pin measures 0.25 inches in diameter and 3 inches in usable length. The hammerlock design allows the legs to lock against each other after bending, providing a more secure hold than a standard hairpin or slotted cotter pin. It is a commonly stocked fastener installed by millwrights, maintenance technicians, and mechanical contractors during equipment assembly and field repair work.

This hammerlock cotter pin is suited for general-purpose fastening in agricultural equipment, industrial machinery, hydraulic cylinder linkages, and trailer hitch assemblies. Its zinc plating provides basic corrosion resistance for light-duty outdoor or shop environments. The 3-inch usable length accommodates a range of clevis and shaft diameters commonly found in trade and maintenance applications.

Key Features

• Hammerlock design locks legs together after installation for improved retention
• Grade 2 steel construction for reliable strength in general-purpose mechanical use
• Zinc-plated finish provides basic corrosion resistance
• 0.25 inch diameter and 3 inch usable length for broad fitment across common clevis and shaft sizes
• Single-piece cotter pin — no tools required for installation beyond standard pliers

Compatibility

Designed as a general-purpose hammerlock cotter pin for use in agricultural, industrial, and mechanical linkage applications requiring a 0.25 inch diameter cotter pin with a 3 inch usable length.

Installation Notes

Hammerlock cotter pins are installed by maintenance technicians and mechanical contractors using standard needle-nose or lineman pliers. Ensure the mating clevis pin or shaft hole is clean and free of burrs before insertion. After passing the pin through the hole, bend the legs back and lock them together using the hammerlock configuration. Always replace a cotter pin that has been removed — do not reuse a previously bent pin.
