Earnest’s USS Hardened Washers are otherwise known as Wide Heat Treated Washers, Wide Through Hardened Washers, and Wide Hardened Washers. The USS Hardened Washers are through hardened for Grade 8 or better applications — preventing imbedding or distortion to the washer and material being clamped. Without washers, bolts and screws can lose their clamping load if they imbed into the clamping material. The washer provides a smooth level and wide protective bearing surface to tighten nuts and bolts.
