Hardened washers are made physically stronger through hardening or carburizing, but are generally smaller in size than your standard washer. Hardened flat washers are designed with extra strength and can be used with Grade 8 bolts and other heat-treated fasteners.

Hardened steel washers are high-strength fasteners designed to provide superior load distribution and prevent wear in demanding applications. These washers are heat-treated to achieve maximum hardness and durability, making them ideal for use in heavy machinery, construction, and automotive assemblies. By offering increased resistance to deformation and corrosion, hardened steel washers ensure reliable and long-lasting performance in high-stress environments.
