Overview
The Zinc Plated Carbon Steel Cotter Pin is a fundamental industrial fastener engineered for secure locking and retention in mechanical assemblies. This pin is designed to pass through a drilled hole in a shaft or clevis pin, with its prongs then bent outward to prevent disengagement. The combination of robust carbon steel and a protective zinc finish delivers reliable performance in a wide array of demanding applications, from heavy machinery to agricultural equipment. Supplied in a bulk package, this cotter pin offers cost-effective inventory for maintenance, repair, and production operations.
