Value Collection -38277-21/2 Hammerlock Cotter Pin

Product Description

The VALUE COLLECTION -38277-21/2 is a hammerlock cotter pin designed for mechanical fastening applications where a secure, removable locking method is required. Measuring 5/16 inch in diameter and 2.5 inches in length, this pin is manufactured from Grade 2 steel with a zinc-plated finish that provides corrosion resistance in light-duty service environments. Hammerlock cotter pins are commonly installed by millwrights, maintenance technicians, and general tradespeople working on machinery, agricultural equipment, structural assemblies, and trailer hitches. The zinc plating helps resist oxidation during storage and in outdoor or moisture-exposed applications.

This hammerlock cotter pin is suited for residential, commercial, and light industrial mechanical assemblies where a fast-install, reusable locking pin is called for. Typical applications include pinning clevis ends, securing shaft collars, locking linkage joints on equipment, and fastening trailer hitch assemblies. The hammerlock style allows quick insertion and removal without tools, making it practical for field maintenance and routine service work. This pin ships in a package quantity of 25 units, useful for stocking maintenance carts or shop inventories.

Installation Notes

Installation is typically performed by maintenance technicians or tradespeople as part of mechanical assembly or field service work. Always de-energize and lock out any powered equipment before inserting or removing cotter pins from moving assemblies. Ensure the pin hole diameter and pin length are compatible with the receiving clevis or shaft before installation. Inspect pins for deformation or wear before reuse and replace any pin that shows bending, cracking, or corrosion that may compromise locking integrity.
