    Grade 8 USS Thick Flat Washer Zinc Plated 7/8

    Part #: FW8-USS-7/8

    This Grade 8 USS thick flat washer is engineered for 7/8-inch bolts and made from through-hardened alloy steel for superior tensile strength and durability. It features a yellow zinc chromate finish for moderate corrosion resistance and complies with ASME B18.21.1 standards. Its wide bearing surface distributes loads evenly, minimizes damage to materials, and helps prevent loosening under vibration or dynamic forces.
