| Low carbon USS flat washers serve multiple purposes, such as increasing the bearing surface area under bolt heads or nuts, protecting against distortion during rotation, providing tightness to joints to prevent leakage, and evenly distributing pressure under bolt or nut heads. These washers adhere to dimensional standards outlined in ASME B18.21.1. Notably, USS flat washers, distinguished by their larger outer diameter compared to SAE flat washers, are versatile and suitable for various applications. Their specifications fall under ASTM F844, which covers unhardened steel flat washers designed for general use. |
