Value Collection 79529889 Extended Prong Cotter Pin 75 Pack

Product Description

The VALUE COLLECTION 79529889 is a zinc-plated, extended prong cotter pin manufactured from Grade 2 steel. It measures 0.125 inches in diameter and 1.25 inches in length. Extended prong cotter pins are used to secure pins, bolts, and fasteners in mechanical assemblies by bending the prongs back after insertion to lock the fastener in place. The zinc plating provides basic corrosion resistance suitable for general-purpose applications. This listing covers a package of 75 pins, making it a practical bulk supply for shop use, maintenance kits, or field service work.

This cotter pin is suited for light-duty mechanical and industrial applications where a reliable, non-threaded locking fastener is required. Common use cases include securing clevis pins, castle nuts, and shaft pins in equipment assemblies across HVAC, plumbing, electrical, and general mechanical trades. The extended prong design provides additional material beyond the eye loop, allowing a wider spread on the prongs for more positive retention in the mating hole.

Compatibility

Designed as a general-purpose extended prong cotter pin for use in light mechanical assemblies requiring a 0.125-inch diameter pin hole.

Installation Notes

Cotter pins are installed by a mechanic or technician after inserting through the cross-drilled hole of a pin or fastener. Once seated, bend the prongs apart using needle-nose pliers to lock the pin in place. Never reuse a cotter pin that has been bent; always install a new pin on reassembly. Ensure the mating hole diameter matches the pin diameter before installation to avoid loose fit or difficulty spreading the prongs.
