Value Collection P20128 Hammerlock Cotter Pin

Product Description

The VALUE COLLECTION P20128 is a hammerlock cotter pin designed for mechanical fastening applications where a low-profile, self-locking retention method is required. Measuring 1/16 inch in diameter and 1/2 inch in length, this pin is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in mild environments. Hammerlock cotter pins are commonly used to secure clevis pins, clevises, and shaft assemblies in light-duty mechanical systems. The zinc plating protects the steel substrate and allows the pin to function reliably in both indoor and sheltered outdoor installations.

This cotter pin is suited for light mechanical assembly work across maintenance, repair, and manufacturing operations. Typical applications include securing pins in agricultural equipment linkages, light machinery, conveyor components, and general fabrication assemblies where a reusable or single-use retention fastener is needed. Installers in HVAC, plumbing, and mechanical trades also use this style of pin in damper linkages, actuator clevis connections, and bracket retention assemblies.

Key Features

• Hammerlock style provides a secure, low-profile pin retention without requiring additional tools for basic insertion
• Grade 2 steel construction suitable for light- to medium-duty mechanical fastening loads
• Zinc-plated finish offers basic corrosion resistance for indoor and sheltered environments
• Compact 1/16 inch diameter and 1/2 inch length fits standard small clevis and shaft pin applications
• UNSPSC Code 31163204 for procurement and catalog classification

Compatibility

Designed as a standard hammerlock cotter pin replacement for light mechanical assemblies requiring a 1/16 inch diameter, 1/2 inch long retention pin in Grade 2 zinc-plated steel.

Installation Notes

Installation is typically performed by maintenance technicians or mechanical assemblers using standard hand tools. Ensure the receiving pin hole is clean and sized correctly for a 1/16 inch cotter pin before insertion. Depressurize, de-energize, or lock out any mechanical system before replacing retention hardware in live assemblies. Hammerlock cotter pins are generally considered single-use fasteners and should be replaced rather than reused once removed.
