Professional Applications & Engineering Value

These Grade 8 split lock washers deliver exceptional engineering value in demanding industrial environments where vibration-induced fastener failure is a critical concern. The zinc yellow-chromate plated steel construction provides dual protection against corrosion while maintaining the Rockwell C38 hardness necessary for repeated compression cycles. The standard split lock washer design creates continuous spring tension that counters rotational forces in heavy machinery, automotive assemblies, and structural applications. Engineered to ASME B18.21.1 standards, these washers ensure precise fit with 1/2" fasteners while the REACH compliance addresses environmental regulations without compromising performance in industrial settings.

Specification Summary & Compliance

This split lock washer features precise dimensions of 0.512" ID, 0.869" OD, and 0.125" thickness, manufactured to ASME B18.21.1 specifications for dimensional accuracy and performance reliability. The component meets Grade 8 strength requirements with Rockwell C38 hardness and is fully REACH compliant (EC 1907/2006) regarding substance restrictions. The zinc yellow-chromate plating provides both corrosion protection and consistent performance in industrial fastener applications.
