Professional Applications & Engineering Value
This Grade 8 split lock washer delivers critical engineering solutions where vibration-induced loosening threatens assembly integrity. The zinc yellow-chromate plated steel construction provides dual protection against corrosion while maintaining the Rockwell C38 hardness necessary for repeated loading cycles. Engineered specifically for heavy-duty industrial applications, the standard split design creates continuous spring action that compensates for thermal expansion, material relaxation, and impact forces. The precise 2.039" internal diameter ensures optimal fit on 2" fasteners, making these industrial washers ideal for construction equipment, manufacturing machinery, transportation systems, and other high-vibration environments where fastener security is non-negotiable.
Specification Summary & Compliance
Manufactured to exact ASME B18.21.1 specifications for standard split lock washers, this product features precise dimensional tolerances with 2.039" ID, 3.144" OD, and 0.496" thickness. The Grade 8 strength classification and Rockwell C38 hardness ensure consistent performance in demanding applications. Compliant with REACH regulations (EC 1907/2006) regarding substance restrictions, this washer meets current environmental standards while delivering reliable mechanical locking performance for industrial fastening systems.
