Professional Applications & Engineering Value
Engineered for demanding industrial applications, this SAE flat washer solves critical challenges in heavy machinery, construction equipment, and automotive assemblies. The zinc yellow-chromate plated steel construction provides dual protection against corrosion and abrasion, significantly reducing maintenance frequency in exposed environments. With Grade 8 strength classification and Rockwell C38 hardness, it maintains structural integrity under extreme vibrational loads and high tension fastening. The precise 3/4" screw size compatibility and ASME-standard dimensions ensure perfect fitment in inch system assemblies, preventing joint failure while distributing clamp load effectively across connected surfaces.
Specification Summary & Compliance
This flat washer meets ASME B18.21.1 dimensional and mechanical specifications with precise ID (0.812") and OD (1.469") tolerances. Manufactured from high-strength steel with zinc yellow-chromate plating surface treatment, it achieves Rockwell C38 hardness and Grade 8 fastener strength classification. The product is fully REACH compliant (EC 1907/2006) regarding substance restrictions and demonstrates conformity with industrial inch system measurement standards for reliable performance in global applications.
