Value Collection 40961 Extended Prong Cotter Pin

Product Description

The VALUE COLLECTION 40961 is a zinc-plated steel extended prong cotter pin designed for use in mechanical assemblies where a reliable, removable fastener is required to secure clevis pins, shaft pins, and similar components. Measuring 0.375 inches in diameter and 3 inches in usable length, this cotter pin provides positive retention in a wide range of light- to medium-duty fastening applications. The zinc plating offers baseline corrosion resistance for general indoor and outdoor service environments. Installation and removal require no special tooling and can be performed quickly during routine maintenance or repair work.

Extended prong cotter pins are commonly used in agricultural equipment, trailers, linkage assemblies, HVAC damper linkages, plumbing valve actuators, and general mechanical fabrication. The extended prong design allows for easier bending and locking after insertion compared to standard prong styles, making it a practical choice in high-turnover service scenarios where pins must be replaced frequently. This pin is sized for applications requiring a 0.375-inch diameter fastener with a 3-inch usable length.

Key Features

• Extended prong design for easier post-insertion bending and secure locking
• 0.375-inch diameter fits standard clevis and shaft pin bores sized for 3/8-inch cotter pins
• 3-inch usable length accommodates thicker assemblies and linkage hardware
• Zinc-plated steel construction provides corrosion resistance for general service conditions
• No special tools required for installation or removal

Compatibility

Designed as a general-purpose replacement extended prong cotter pin for mechanical assemblies requiring a 0.375-inch diameter, 3-inch usable length fastener in steel with zinc-plated finish.

Installation Notes

Cotter pins are typically installed by mechanical technicians, maintenance personnel, or field service professionals as part of pin-and-clevis or shaft retention assemblies. Before replacing a cotter pin, relieve any load on the assembly and ensure the retaining pin or bolt is fully seated. Insert the cotter pin through the aligned hole and bend the prongs outward using needle-nose pliers to lock it in place. Always replace a cotter pin that has been removed rather than reusing it, as repeated bending compromises the metal.
