Value Collection 2537 Hair Pin Cotter 0.75-1 in Shaft

Product Description

The VALUE COLLECTION 2537 is a hair pin cotter pin designed to secure shafts ranging from 0.75 inches to 1 inch in diameter. Manufactured from Grade 2 spring steel with a zinc-plated finish, this fastener provides reliable retention and corrosion resistance in light- to medium-duty mechanical assemblies. The wire diameter measures 0.25 inches, and the overall pin length is 3.9375 inches. It is used wherever a quick-install, reusable shaft retention solution is needed. Millwrights, maintenance technicians, HVAC service techs, and general tradespeople install this type of fastener in equipment linkages, clevis connections, and mechanical drive assemblies.

This hair pin cotter is suited for residential and light commercial mechanical applications where shafts in the 0.75-inch to 1-inch range require positive retention without threaded hardware. Common install scenarios include linkage rods, pivot pins, and clevis assemblies found in HVAC damper controls, pump mounts, and general equipment maintenance. The zinc-plated finish offers baseline protection against oxidation in indoor and sheltered outdoor environments. No special tooling is required for installation or removal, making it a practical choice for field service work.

Compatibility

Designed as a general-purpose hair pin cotter replacement for mechanical assemblies using shafts between 0.75 inches and 1 inch in diameter, including linkage rods, clevis pins, and pivot assemblies in HVAC and light industrial equipment.

Installation Notes

Installation does not require specialized tools — the spring steel construction allows the pin to be pressed onto the shaft by hand or with light pliers. Always de-energize and lock out equipment before servicing any mechanical linkage or drive assembly. Inspect the pin for deformation or loss of spring tension before reuse. Follow applicable equipment manufacturer guidelines and relevant safety codes when servicing mechanical assemblies.
