Professional Applications & Engineering Value
These Grade 8 flat washers deliver critical engineering solutions where high-strength and corrosion resistance are paramount. The zinc yellow-chromate plated steel construction provides superior protection against rust and chemical exposure, making them ideal for heavy-duty industrial applications including construction equipment, automotive assemblies, and machinery manufacturing. The precise SAE inch dimensions (1/2" screw size compatibility) ensure perfect fitment, while the Rockwell C38 hardness maintains structural integrity under extreme loads. These ASME B18.21.1 compliant washers solve common fastener failure points by distributing clamp load effectively, preventing joint relaxation, and extending equipment service life in demanding operating conditions.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 standards with precise dimensional tolerances for inch system applications. Features include: 0.531" ID, 1.062" OD, and thickness range of 0.074-0.121" for optimal performance with 1/2" fasteners. The Grade 8 classification and Rockwell C38 hardness ensure high-strength capabilities. Compliant with REACH (EC 1907/2006) regulations (updated 06/14/2023, 235 SVHC compliant), meeting environmental and safety requirements for industrial use across global markets.
