The Hillman Group 280330 3/4-Inch Flat Washer Hardened, 20-Pack

Product Description Hillman Hardened Flat Washers are heavy-duty fasteners built for high-torque, high-strength bolted joints. Sized for a 3/4 inch bolt, they resist the dishing and embedding that softer washers suffer under heavy clamp load, keeping the connection tight and evenly seated where ordinary washers would deform or sink into the mating surface. Built to the SAE pattern, the hardened body provides a firm, flat bearing surface that spreads heavy clamping force across the joint without collapsing. This makes hardened washers a standard companion to grade 8 and other high-strength bolts, where the fastener is torqued well beyond what a standard washer is designed to handle. A yellow zinc dichromate coating over the hardened steel adds corrosion resistance beyond plain zinc, giving a distinctive gold tone and protecting the washer through demanding indoor and outdoor service. The finish helps the washer stand up to weather and wear in structural and machinery settings over the long term. Use these washers for high-strength bolted connections in structural steel, heavy equipment, machinery, and load-bearing assemblies wherever bolts are torqued to high clamp loads and must stay tight under stress and vibration. This pack provides a ready supply for structural bolting, equipment, and heavy repair projects. From the Manufacturer Used in applications with nuts and bolts. The flat washer provides a greater bearing surface which helps prevent a nut or bolt head from tearing through the material. Flat washers are commonly used in decks and fence building. The called out size is the inner diameter of the washer.
