USS Flat Washers

- One of the most common types of flat washers, National Bolt & Nut’s Type A wide series USS flat washers possess a flat bearing surface underneath the fastener that more evenly distributes pressure. Designed to meet most industrial applications, ranging from maintenance to manufacturing and repair, USS flat washers help prevent a nut, bolt, or screw from pulling through the material. Our USS flat washers meet ANSI B18.22.1 dimensional specifications.
