Value Collection MP40929 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION MP40929 is an extended prong cotter pin designed for secure fastening in mechanical assemblies, clevis joints, and pin retention applications. Manufactured from Grade 2 steel with a zinc-plated finish, this cotter pin measures 5/32 inch in diameter and 1 inch in usable length. The extended prong design allows the legs to be bent back fully after insertion, locking the pin firmly in place and preventing axial movement of shafts, clevis pins, and similar fasteners. Maintenance technicians, millwrights, and general tradespeople install these pins across a wide range of industrial and mechanical service tasks.

This cotter pin is suited for residential and light commercial mechanical applications where a reliable, low-cost pin retention solution is needed. Common installation scenarios include securing clevis pins on linkage assemblies, retaining shaft pins on equipment, and general fastening tasks in HVAC linkage hardware, pump assemblies, and structural brackets. The zinc plating provides basic corrosion resistance for dry to moderately humid environments.

Key Features

• Extended prong design locks firmly after bending, preventing pin walk-out
• Grade 2 steel construction provides adequate shear and bend strength for light-duty fastening
• Zinc-plated finish offers basic corrosion resistance in dry and moderately humid conditions
• 5/32 inch diameter fits standard clevis and shaft pin applications of that bore size
• 1 inch usable length accommodates typical clevis pin and bracket thicknesses

Compatibility

Designed as a standard replacement or service cotter pin for mechanical assemblies requiring a 5/32 inch diameter extended prong cotter pin in Grade 2 zinc-plated steel.

Installation Notes

Installation requires no special tools beyond standard needle-nose pliers for spreading the prongs after insertion. Ensure the assembly is de-energized or at rest before inserting or removing cotter pins in any moving linkage. Insert the pin fully through the bore until the head seats, then bend the prongs apart to lock. Do not reuse a previously bent cotter pin, as re-straightening fatigues the steel and reduces retention reliability.
