Value Collection MP40912 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION MP40912 is an extended prong cotter pin designed for securing clevis pins, castle nuts, and fastener assemblies in mechanical, HVAC, plumbing, and general industrial applications. Manufactured from Grade 2 steel with a zinc-plated finish, this cotter pin measures 3/32 inch in diameter and 2 inches in usable length. The extended prong design allows the legs to be bent back easily after insertion, providing a reliable mechanical lock against loosening under vibration or dynamic load. Tradespeople and maintenance technicians use this type of hardware in bracket assemblies, linkage connections, and panel fastening throughout a wide range of equipment installations.

This cotter pin is suited for light-duty to medium-duty fastening tasks where a removable, low-profile locking solution is required. Typical applications include securing pins in HVAC damper linkages, plumbing support brackets, electrical panel assemblies, and general mechanical equipment. The zinc-plated finish provides basic corrosion resistance for use in indoor and protected outdoor environments. It is sold individually, with a minimum order quantity of 50 units per purchase, making it appropriate for shop stock and service van inventory replenishment.

Compatibility

Designed as a standard replacement or stock cotter pin for mechanical fastener assemblies requiring a 3/32 inch extended prong pin with a 2 inch usable length.

Installation Notes

Installation requires no special tools beyond a pair of needle-nose pliers for bending the prongs after insertion. Always ensure the corresponding clevis pin or castle nut bore diameter matches the 3/32 inch pin gauge before installation. Compress or align the assembly fully before inserting the cotter pin through the hole, then spread the prongs to lock in place. Do not reuse a cotter pin that has been previously bent or deformed.
