    USS 5/16-Inch Flat Washer Zinc Plated Steel

    Part #: FW-USS-5/16

    The USS 5/16-inch flat washer provides a large bearing surface for distributing loads evenly under 5/16-inch bolts and nuts, preventing material deformation and bolt pull-through. Built to USS specifications, it offers a greater outer diameter than SAE washers for enhanced load stability. Crafted from zinc-plated steel, it resists corrosion and ensures durability in automotive, construction, and industrial fastening applications.
