    Grade 8 USS Thick Flat Washer Zinc Plated 3/4

    Part #: FW8-USS-3/4

    This Grade 8 USS thick flat washer fits 3/4-inch bolts and is made from high-strength, through-hardened alloy steel with a yellow zinc chromate finish for moderate corrosion resistance. It provides a wide bearing surface to evenly distribute loads, protect joint materials, and prevent loosening under vibration. It meets ASME B18.21.1 dimensional and mechanical requirements for Grade 8 fasteners.
