Professional Applications & Engineering Value

These Grade 8 zinc-plated steel flat washers deliver critical engineering solutions for industrial applications where corrosion resistance and mechanical strength are paramount. The zinc plating provides essential protection against environmental degradation, while the Rockwell C38 hardness ensures the washers maintain their structural integrity under extreme pressure. Engineered specifically for 1/2" fasteners with precise 1" OD dimensions, these washers effectively distribute clamping force across wider surfaces, preventing material deformation and maintaining joint stability in heavy machinery, construction equipment, and industrial assemblies. The inch system compatibility makes them ideal for North American industrial specifications where dimensional precision and ASME B18.21.1 compliance are required for quality assurance and safety standards.

Specification Summary & Compliance

Manufactured to exact ASME B18.21.1 standards with precise dimensional tolerances: 0.531" inner diameter, 1" outer diameter, and thickness ranging 0.056-0.071". Constructed from zinc-plated steel with Rockwell C38 hardness and classified as Grade 8 for high-strength applications. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use across industrial sectors.
