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