Professional Applications & Engineering Value
This Grade 8 flat washer delivers critical engineering solutions for industrial applications where corrosion resistance and structural integrity are paramount. The zinc-flake coated steel construction provides superior protection against environmental degradation, making it ideal for outdoor equipment, automotive assemblies, and heavy machinery exposed to moisture and chemicals. With its SAE designation and inch system measurements, this washer ensures perfect compatibility with standard 1 1/8" screw size fasteners in North American industrial applications. The combination of Rockwell C38 hardness and precise dimensional tolerances prevents loosening under vibration and maintains consistent clamping force, addressing common failure points in high-stress assemblies while meeting rigorous industrial washer requirements.
Specification Summary & Compliance
Manufactured to exact ASME B18.21.1 standards with dimensional specifications including 1.262" ID, 2.243" OD, and thickness range of 0.146-0.177". The washer meets Grade 8 strength classification requirements with Rockwell C38 hardness verification. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory adherence for global industrial applications.
