Cotter Pin Carbon Steel Zinc CR+3 (Inch)
Our Carbon Steel Cotter Pins with Zinc CR+3 plating provide reliable, corrosion‑resistant mechanical locking for a wide variety of fastening applications. Manufactured from quality carbon steel, these cotter pins are designed to secure clevis pins, shafts, castle nuts, and other components by simple insertion and spreading of the prongs, creating a dependable retention solution.
The Zinc CR+3 (trivalent chromium) finish offers enhanced corrosion resistance compared to traditional zinc coatings, along with a clean, bright appearance. This finish makes these cotter pins well suited for indoor and light‑to‑moderate outdoor use where protection against rust and environmental exposure is required. Their consistent sizing and smooth surface allow for easy installation and long service life in industrial, automotive, agricultural, and general hardware applications.
Designed for durability and ease of use, our Zinc CR+3 Carbon Steel Cotter Pins are widely used in machinery maintenance, automotive assemblies, farm equipment, trailer components, and general mechanical repairs. The zinc coating helps extend service life while maintaining reliable holding strength in vibration‑prone applications. Available in a full range of diameters and lengths, these cotter pins provide a cost‑effective, corrosion‑resistant locking solution for OEMs, maintenance teams, and industrial users.
