Value Collection 79529871 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION 79529871 is an extended prong cotter pin designed to secure fasteners, clevis pins, and shafts in mechanical assemblies where reliable locking is required. The pin measures 0.125 inches in diameter with a 1-inch usable length and is manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. Extended prong cotter pins are driven through a drilled hole and bent outward to lock a fastener in place. Maintenance technicians, millwrights, and general mechanics install these pins across a wide range of industrial, agricultural, and equipment service applications.

This cotter pin is suited for light- to medium-duty mechanical assemblies where a positive, low-cost locking solution is needed. Common applications include securing axle pins, linkage rods, clevis assemblies, and hinged components on industrial equipment and agricultural machinery. The zinc plating provides a level of protection against moisture and light corrosion in standard indoor or sheltered outdoor environments. Sold in a package quantity of 75, this pin is practical for shops and field service kits that need a ready supply on hand.

Installation Notes

Cotter pins are installed by general mechanics, maintenance technicians, and millwrights using standard needle-nose pliers or cotter pin tools. Always de-energize or disable the equipment and relieve any load on the assembly before removing or installing a cotter pin. Insert the pin fully through the drilled hole so both prongs extend beyond the fastener, then bend the prongs apart to lock. Cotter pins are single-use fasteners and should not be straightened and reused after removal.
