Heat Treated Alloy Steel - Yellow Zinc Plated
Grade 8 SAE Flat Washers are manufactured from High Strength Alloy Steel.  It is recommended that a Grade 8 Flat Washer be used with Grade 8 Nuts and Bolts.  Grade 8 Washers do not crush and deform when torque is applied in tightening.
SAE Flat Washers fit tighter on a Bolt than a USS
Flat Washer, as they have a smaller I.D. (Internal Diameter).
The O.D. (Outer Diameter) of a SAE Washer is also smaller than that of a USS Flat Washer.
