Value Collection -38278-4 Hammerlock Cotter Pin

Product Description

The VALUE COLLECTION -38278-4 is a hammerlock cotter pin designed for securing clevis pins, clevises, and linkage assemblies in light-duty mechanical applications. It measures 0.375 inches in diameter with a usable length of 4 inches. Constructed from Grade 2 steel with a zinc-plated finish, this pin resists corrosion in typical shop and field environments. Hammerlock cotter pins provide a positive, low-profile lock that can be installed and removed with basic hand tools. Technicians across HVAC, plumbing, and general mechanical service use this style of pin to secure components in control linkages, damper assemblies, and equipment frames.

This cotter pin is suited for residential and light commercial mechanical service where a reliable, removable fastener is required. It fits standard clevis and pin applications that call for a 0.375-inch diameter cotter pin with a 4-inch usable length. The zinc-plated finish makes it appropriate for use in covered or semi-exposed environments where mild corrosion resistance is needed.

Compatibility

Designed as a standard replacement or stock hammerlock cotter pin for light-duty mechanical assemblies requiring a 0.375-inch diameter pin with a 4-inch usable length.

Installation Notes

Hammerlock cotter pins are typically installed and removed by hand or with standard pliers. Before servicing any linkage or assembly, de-energize or lock out the equipment per applicable safety procedures. Ensure the clevis pin hole diameter is compatible with the 0.375-inch pin before installation. Inspect the pin and mating components for wear or damage before reuse.
