Value Collection 40958 Extended Prong Cotter Pin 5/16x4in

Product Description

The VALUE COLLECTION 40958 is a Grade 2 steel extended prong cotter pin designed to secure fasteners, clevis pins, and shaft assemblies in mechanical and structural applications. The pin measures 5/16 inches in diameter and 4 inches in usable length, with a zinc-plated finish that provides corrosion resistance in light-duty service environments. The extended prong design allows the legs to be bent back firmly after installation, creating a positive lock that resists vibration-induced loosening. Technicians and mechanics in HVAC, plumbing, and general industrial trades reach for this type of pin wherever a removable yet vibration-resistant fastening solution is required.

This cotter pin is suited for residential and light commercial maintenance work, equipment assembly, and field repairs. Typical applications include securing clevis pins on linkage assemblies, retaining shaft collars, and locking castellated nuts on threaded fasteners. The zinc plating makes it appropriate for indoor or sheltered outdoor use where minor moisture exposure is possible. This product is sold individually and is subject to a minimum order quantity of 50 units per order.

Designed as a standard extended prong cotter pin for use in mechanical assemblies, linkage systems, and equipment requiring a 5/16 inches diameter pin with a 4 inches usable length.

Installation Notes

Cotter pins are typically installed by maintenance technicians, millwrights, or HVAC service professionals using needle-nose pliers or cotter pin tools. Always insert the pin through a fully aligned hole and spread the prongs firmly against the fastener face to prevent backing out. Remove and replace the cotter pin any time a joint is disassembled — cotter pins are single-use fasteners and should never be straightened and reused. Ensure the mating pin or fastener is fully depressurized or de-energized before performing any work on the assembly.
