Slotted Spring Pin High Carbon Steel Zinc CR+3 (Inch)
Our Slotted Spring Pins made from High Carbon Steel with Zinc CR+3 plating are designed to provide secure, self‑locking retention in mechanical assemblies exposed to vibration, impact, and repeated movement. Manufactured from high‑strength high carbon steel, these spring pins deliver excellent resilience, shear strength, and long service life in demanding industrial and mechanical applications.
The slotted (tension pin) design allows the pin to compress during installation and then expand outward inside the hole, creating a reliable interference fit without additional hardware. The Zinc CR+3 (trivalent chromium) finish offers enhanced corrosion resistance compared to standard zinc coatings, along with a clean, bright appearance suitable for indoor and light‑to‑moderate outdoor environments.
Engineered for durability and dependable performance, our High Carbon Steel Slotted Spring Pins with Zinc CR+3 plating are widely used in machinery, automotive assemblies, industrial equipment, gear mechanisms, linkages, hinges, pulleys, and rotating components. The zinc coating provides added protection against corrosion while maintaining smooth installation and consistent holding power. Available in a broad range of diameters and lengths, these pins offer a cost‑effective fastening solution for OEM manufacturing, maintenance, and repair operations.
