Value Collection P20131 Hammerlock Cotter Pin

Product Description

The VALUE COLLECTION P20131 is a hammerlock cotter pin designed for securing clevis pins, shafts, and fastener assemblies across a wide range of mechanical and industrial applications. Measuring 0.125 inches in diameter and 0.75 inches in length, this cotter pin is manufactured from Grade 2 steel with a zinc-plated finish that provides baseline corrosion resistance. The hammerlock style allows the free leg to lock back over the head after installation, eliminating the need to bend legs in the field. Mechanics, millwrights, and maintenance technicians use this type of fastener wherever a quick, reliable pin retention solution is required.

This cotter pin is suited for light-duty to medium-duty fastening tasks in agricultural equipment, automotive assemblies, HVAC linkage hardware, and general industrial machinery. The compact 0.75-inch length makes it appropriate for thin-clevis or close-tolerance applications where a standard bent-leg cotter pin would not fit. The zinc plating adds a layer of protection against mild moisture exposure in indoor or sheltered outdoor installations.

Key Features

• Hammerlock design locks back on itself without field bending
• 0.125-inch diameter suits standard clevis and shaft-pin applications
• Grade 2 steel construction provides adequate tensile strength for light-to-medium duty use
• Zinc-plated finish resists mild corrosion in sheltered environments
• 0.75-inch body length fits close-tolerance and thin-clevis assemblies

Compatibility

Designed as a general-purpose hammerlock cotter pin for use in mechanical linkages, clevis assemblies, and fastener retention applications requiring a 0.125-inch pin diameter.

Installation Notes

Installation requires no special tools beyond basic hand tools. Ensure the mating hole diameter matches the pin diameter before insertion to prevent slop or binding. After seating the pin, press the free leg over the head to engage the hammerlock. Always relieve load from the assembly and follow applicable safety lockout procedures before servicing any pinned connection.
