    Grade 8 USS Thick Flat Washer Zinc Plated 7/16

    Part #: FW8-USS-7/16

    This Grade 8 USS thick flat washer is designed for 7/16-inch bolts and constructed from through-hardened alloy steel for exceptional tensile strength. The yellow zinc chromate finish provides moderate corrosion resistance while the washer meets ASME B18.21.1 specifications for dimensions and mechanical properties. Its large bearing surface ensures even load distribution, reduced surface wear, and resistance to loosening under vibration.
