Split Lock Washers, Hi Collar, Thru Hardened, Zinc Yellow (Inch)
Hi Collar Split Lock Washers that are thru hardened and finished with Zinc Yellow are designed for high-strength fastening applications requiring superior locking performance and added corrosion protection. Their elevated collar profile provides increased bearing surface, making them ideal for socket head cap screws and other fasteners with smaller contact areas. The Zinc Yellow plating offers enhanced rust resistance and high visibility during assembly.
The hardened steel construction delivers excellent durability and resistance to deformation, while the split-ring design creates spring tension to prevent loosening under vibration, shock, or dynamic loads. These washers are commonly used in industrial machinery, automotive assemblies, precision equipment, and high-performance mechanical systems where dependable locking action and corrosion protection are essential.
