FEATURES

 

Flat Washers provide spacing and an increased bearing surface. SAE Flat Washers offer a tighter screw fit and a thinner washer with a smaller outside diameter (OD) than comparably sized USS washers. Use Through Hardened SAE Flat Washers with Grade 5 and Grade 8 fasteners. Washer size refers to its nominal hole size and is based on screw size. See our SAE Washer Dimensions reference chart.
