Professional Applications & Engineering Value
This SAE flat washer delivers exceptional engineering value through its black corrosion-resistant coating and steel construction, specifically designed to address common industrial challenges. The protective coating significantly reduces oxidation and degradation in moisture-prone environments, while the precise dimensional specifications ensure proper load distribution across mating surfaces. These industrial washers prevent fastener embedment, reduce galvanic corrosion risks, and maintain clamping force integrity in heavy-duty assemblies. Engineered to ASME B18.21.1 standards, they provide reliable performance in machinery, structural connections, and equipment where consistent washer geometry and corrosion resistance are critical for long-term operational reliability.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 specifications with precise dimensional tolerances including 0.812" inner diameter, 1.469" outer diameter, and thickness range of 0.108-0.160". This flat washer complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory compliance for industrial applications worldwide. The inch-system measurement and SAE designation provide compatibility with standard 3/4" fasteners and industrial equipment specifications.
