Sized for a 1-1\/4 inch\nbolt, they resist the dishing and embedding that softer washers suffer under\nheavy clamp load, keeping the connection tight and evenly seated where\nordinary washers would deform or sink into the mating surface. Built to the\nUSS pattern, the hardened body provides a firm, flat bearing surface that\nspreads heavy clamping force across the joint without collapsing. This makes\nhardened washers a standard companion to grade 8 and other high-strength\nbolts, where the fastener is torqued well beyond what a standard washer is\ndesigned to handle. A yellow zinc dichromate coating over the hardened steel\nadds corrosion resistance beyond plain zinc, giving a distinctive gold tone\nand protecting the washer through demanding indoor and outdoor service. The\nfinish helps the washer stand up to weather and wear in structural and\nmachinery settings over the long term. Use these washers for high-strength\nbolted connections in structural steel, heavy equipment, machinery, and load-\nbearing assemblies wherever bolts are torqued to high clamp loads and must\nstay tight under stress and vibration. This pack provides a ready supply for\nstructural bolting, equipment, and heavy repair projects. From the\nManufacturer Used in applications with nuts and bolts. The flat washer\nprovides a greater bearing surface which helps prevent a nut or bolt head from\ntearing through the material. Flat washers are commonly used in decks and\nfence building. The called out size is the inner diameter of the washer.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eHIGH-LOAD BEARING STRENGTH: This hardened flat washer is built for high-torque bolted joints, resisting the dishing and embedding that softer washers suffer under heavy clamp load so the connection stays tight and evenly seated.\u003c\/li\u003e\n \u003cli\u003eHARDENED USS PATTERN FIT: Made to the USS pattern for a 1-1\/4 inch bolt, the hardened body spreads heavy clamping force without deforming, providing a firm, flat bearing surface under high-strength bolts and nuts in structural work.\u003c\/li\u003e\n \u003cli\u003eYELLOW ZINC DICHROMATE FINISH: A yellow zinc dichromate coating over hardened steel adds corrosion resistance beyond standard zinc, protecting the washer in demanding indoor and outdoor structural and machinery applications over time.\u003c\/li\u003e\n \u003cli\u003eSTRUCTURAL AND MACHINERY USE: Ideal for high-strength bolted connections in structural steel, heavy equipment, machinery, and load-bearing assemblies, a dependable choice wherever bolts are torqued to high clamp loads and must stay tight.\u003c\/li\u003e\n \u003cli\u003eTRUSTED HILLMAN QUALITY: Hillman supplies dependable fasteners and hardware that homeowners and pros rely on for everyday projects.
