Hardened Washers

Hardened washers are made physically stronger through hardening or carburizing, but are smaller in size than your standard washer. The extra strength can be used with Grade 8 bolts and other heat-treated fasteners. They are available in F436 Hardness classes and many others to fit various OEM requirements. Willie Washers has these washers in the following hardness ranges: metric hard washers available in HV200, HV300, and other hardness ranges; low carbon steel parts, for which the most common case hardness is 15N 89; and thrust washers available in the RC58/62 range.
