    USS 3/8-Inch Flat Washer Zinc Plated Steel

    Part #: FW-USS-3/8

    The USS 3/8-inch flat washer delivers a wide bearing surface for evenly distributing loads under bolts and nuts, protecting materials and preventing fastener pull-through. Built to USS specifications, it has a larger outer diameter than SAE washers, offering improved load support and stability. Made from durable zinc-plated steel, it resists corrosion and ensures dependable performance in automotive, industrial, and construction applications.
