Regular Split Lock Washer with Clear Zinc Cr3 Plating – Lightweight Corrosion Resistance Meets Reliable Locking Power

When you need dependable locking performance with added protection from corrosion, regular split lock washers with Clear Zinc Cr3 plating are the perfect solution. These washers offer the tried-and-true spring action of a traditional split lock design, with the bonus of a sleek, corrosion-resistant finish that’s ideal for indoor and light outdoor use.

Crafted from medium carbon steel, these washers are heat-treated for durability and resistance to deformation under load. The signature helical split design delivers constant spring tension, effectively helping to resist loosening due to vibration or thermal cycling in bolted assemblies.

The Clear Zinc Cr3 (trivalent) plating provides a brilliant silver finish and moderate corrosion resistance—without the environmental and health risks associated with hexavalent chromium. It’s a RoHS-compliant solution that’s widely accepted in industries like electronics, automotive, HVAC, and general manufacturing.
