Value Collection 79529947 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION 79529947 is an extended prong cotter pin designed for use in mechanical assemblies where a positive locking fastener is required to secure clevis pins, shaft pins, and other fasteners against loosening or disengagement. This pin measures 5/32 inch in diameter and 2 inches in usable length. It is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in light-duty service environments. The extended prong design allows the tines to be bent back easily after installation, creating a secure lock without specialized tooling. Plumbers, millwrights, equipment technicians, and general maintenance tradespeople commonly install these in linkage assemblies, hydraulic cylinders, and mechanical controls.

This cotter pin is suited for use in a wide range of residential and commercial mechanical applications including HVAC linkage assemblies, valve actuators, pump and motor mounts, and general equipment maintenance scenarios. The zinc plating makes it appropriate for dry or lightly humid indoor environments. It is packaged in a quantity of 25 pins per package, making it practical for shop stock or field service kits where multiple fastener replacements may be needed in a single job.

Key Features

• Extended prong design allows tines to be spread and locked after pin insertion without special tooling
• Grade 2 steel construction provides adequate tensile strength for light- to medium-duty fastening applications
• Zinc-plated finish offers basic corrosion resistance in dry and lightly humid environments
• 5/32 inch diameter fits standard clevis and shaft pin holes sized for this pin class
• 2-inch usable length accommodates assemblies with moderate material thickness
• Sold in a 25-piece package to support shop stock and multi-repair service calls

Compatibility

Designed as a standard-size replacement or stock cotter pin for mechanical assemblies requiring a 5/32 inch diameter extended prong cotter pin in light- to medium-duty service.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians. Always depressurize, de-energize, or mechanically lock the assembly before removing or installing cotter pins in load-bearing or actuated linkages. Insert the pin through the hole until the head seats flush, then spread the prongs using needle-nose pliers to secure the pin in place. Never reuse a cotter pin that has been previously bent, as fatigue in the prong material can lead to premature failure.
