The SAE Washers prevent imbedding or distortion to the material being clamped. The washers provide a smooth, level protective bearing surface to fasten nuts and bolts. Without washers, the bolts, nuts, and screws can lose their clamping load if they imbed into the clamping material. SAE Washers are used in assemblies that are bolting together soft metals, wood and steel and are designed to be used with Grade 2 and 5 strength levels fasteners.
