SAE flat washers have slightly smaller inside and outside diameters as compared to USS flat washers. Most SAE washers are made from thinner material. SAE flat washers are designed for assembly around a bolt or screw, between the bearing surface of the fastener and the part to which it is attached. Split lock washers are coiled, hardened, split circular washers with a slightly trapezoidal wire section. The tension generated by the deflection of the regular helical spring lock washer meets the needs of most commercial applications.
