Professional Applications & Engineering Value

Engineered for demanding environments, these Grade 8 SAE flat washers provide critical solutions for industrial fastening challenges. The zinc yellow-chromate plated steel construction delivers outstanding corrosion resistance, protecting against moisture and chemical exposure in outdoor or high-humidity settings. With Rockwell C38 hardness and precise dimensional tolerances, they effectively distribute clamping force, prevent bolt embedment, and resist deformation under heavy loads. Ideal for 5/8" screw applications in construction equipment, automotive assemblies, and heavy machinery, these washers ensure long-term joint integrity, reduce maintenance frequency, and enhance overall fastener system reliability while complying with industry standards.

Specification Summary & Compliance

This SAE flat washer maintains exact inch-system dimensions: 0.656" inner diameter, 1.312" outer diameter, and 0.122-0.146" thickness range for consistent performance. Manufactured to Grade 8 strength standards with Rockwell C38 hardness verification, it meets rigorous mechanical requirements. The product is REACH (EC 1907/2006) compliant as of June 14, 2023, containing no SVHCs above threshold levels, ensuring environmental and safety adherence for global industrial use.
