Professional Applications & Engineering Value
These USS flat washers deliver critical engineering solutions where corrosion resistance and load distribution are paramount. The black corrosion-resistant coated steel construction specifically addresses oxidation and chemical exposure challenges in outdoor installations, marine environments, and industrial facilities. With their substantial 2.5" OD surface area, these heavy-duty flat washers effectively prevent bolt head embedment into soft materials and distribute clamping forces evenly across connected surfaces. The precise 1.062" ID ensures perfect alignment with 1" screw sizes, eliminating installation errors while the robust thickness range maintains performance under dynamic loading conditions. Ideal for structural steel connections, machinery assembly, and infrastructure projects requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
Manufactured to exact ASME B18.21.1 dimensional specifications with inner diameter of 1.062", outer diameter of 2.5", and thickness ranging 0.136-0.192". These USS flat washers are designed specifically for 1" screw applications within the inch measurement system. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards ensures unrestricted use across regulated markets while maintaining the mechanical properties required for demanding industrial applications.
