Value Collection 40926 Extended Prong Cotter Pin Zinc Steel

Product Description

The VALUE COLLECTION 40926 is a zinc-plated steel extended prong cotter pin used to secure fasteners, pins, and shafts in mechanical assemblies. Measuring 0.125 inches in diameter and 2.5 inches in length, this cotter pin features extended prongs that spread and lock in place after installation, providing reliable retention in through-hole applications. The zinc plating provides corrosion resistance suitable for general-purpose indoor and light outdoor use. Machinists, maintenance technicians, and assembly workers install this type of fastener across a wide range of equipment and structural applications.

Extended prong cotter pins are used wherever a positive mechanical lock is needed to prevent axial movement of a pin or bolt. Common applications include agricultural equipment, industrial machinery, trailers, linkage assemblies, and general MRO work. The extended prong design offers additional grip depth compared to standard hammer-lock styles, making it well suited for assemblies subject to vibration or repeated movement cycles.

Key Features

• Extended prong design locks securely after bending, resisting loosening under vibration
• Zinc-plated finish provides light corrosion protection for general-purpose use
• Steel construction offers solid mechanical strength for standard fastening applications
• 0.125 inch diameter fits standard cotter pin holes in that size range
• 2.5 inch length accommodates a range of pin and bolt shank thicknesses

Compatibility

Designed as a general-purpose extended prong cotter pin suitable for standard through-hole fastening applications in agricultural, industrial, and mechanical assembly contexts where a 0.125 inch diameter cotter pin is specified.

Installation Notes

Installation is performed by inserting the pin through the drilled hole in a shaft or bolt, then spreading the prongs apart with needle-nose pliers to lock the pin in place. Always ensure the hole diameter matches the pin diameter before insertion to avoid distortion. Remove existing cotter pins before reinstalling or reusing the fastener assembly, and never reuse a bent or deformed cotter pin. Depressurize or de-energize any associated assembly before performing fastener service.
