Professional Applications & Engineering Value
These Grade 8 SAE flat washers provide critical engineering solutions for industrial applications where vibration resistance and surface protection are paramount. The zinc yellow-chromate plated steel construction offers superior corrosion resistance, making them ideal for outdoor equipment, automotive assemblies, and machinery exposed to moisture or chemicals. Their precise dimensions (0.156" ID, 0.375" OD) ensure perfect compatibility with No. 6 screws, preventing loosening under dynamic loads. The controlled thickness variation maintains consistent clamping force distribution, protecting sensitive surfaces from damage while the ASME B18.21.1 compliance guarantees reliable performance in standardized fastener systems. These industrial flat washers deliver long-term value by reducing maintenance frequency and preventing premature fastener failure in critical applications.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 standards with precise dimensional tolerances including 0.156" inner diameter, 0.375" outer diameter, and thickness range of 0.036-0.045". Constructed from high-strength Grade 8 steel with zinc yellow-chromate plating for enhanced durability. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries and international markets.
