Value Collection CD550530 Cotter Pin 2.5mm X 25mm 100 Pack

Product Description

The VALUE COLLECTION CD550530 is an extended prong cotter pin designed for use in mechanical assemblies where positive locking and retention of fasteners, pins, and clevis hardware is required. Manufactured from Grade 2 steel with a zinc-plated finish, this cotter pin resists corrosion in light-duty service environments. The extended prong design allows the legs to be bent back securely after installation, providing reliable retention without the risk of backing out under vibration. This item is sold in a package quantity of 100, making it suitable for shop stock, maintenance bins, and production assembly applications. Mechanics, millwrights, and general maintenance technicians are the typical installers.

This cotter pin is suited for residential, commercial, and light industrial maintenance applications where a 2.5mm diameter fastener hole is present. Common uses include securing castle nuts, clevis pins, shaft retainers, and linkage hardware in mechanical, agricultural, and general fabrication settings. The package quantity of 100 supports high-turnover shop environments and bulk fastener inventory programs.

Compatibility

Designed as a standard extended prong cotter pin for use in mechanical assemblies requiring a 2.5mm diameter cotter pin hole. Confirm hole diameter and material requirements before installation.

Installation Notes

Cotter pins are installed by mechanics and maintenance technicians using standard pliers or needle-nose pliers. Insert the cotter pin fully through the hole, then spread the prongs by bending them in opposite directions to lock the pin in place. Always replace cotter pins after removal — they are single-use fasteners and should never be reused once bent. Confirm the mating hole diameter matches the pin diameter before installation to ensure proper fit and retention.
