Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this Grade 8 SAE flat washer delivers critical performance where vibration resistance and joint integrity are paramount. The zinc-flake coated steel construction combats corrosion in manufacturing, automotive, and construction environments, while the precise 0.599" ID and 1.168" OD dimensions ensure perfect fit with 9/16" fasteners. Its Rockwell C38 hardness prevents deformation under high clamp loads, solving common issues of fastener loosening and material fatigue. By meeting ASME B18.21.1 standards, it provides reliable performance in machinery assembly, structural connections, and equipment maintenance where SAE flat washers are specified.
Specification Summary & Compliance
This SAE flat washer maintains precise dimensional tolerances per ASME B18.21.1 specifications with 0.599" inner diameter, 1.168" outer diameter, and thickness ranging 0.074-0.121". Manufactured from zinc-flake coated steel with Rockwell C38 hardness, it meets Grade 8 strength requirements for high-stress applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and material restrictions adherence.
