Hardened
Hardened washers are washers that have been heat-treated to achieve increased hardness and strength. Unlike standard washers, hardened washers are specifically designed to withstand higher stress, wear, and impact, making them suitable for demanding applications where durability and resistance to deformation are critical. Made and stamped with identification to ASTM F436.
