This washer follows USS (United States Standard) dimensional standards, providing a larger outer diameter relative to the screw size compared to SAE washers, which distributes load more effectively across the mating surface. With an inside diameter of 1.055 inches, an outside diameter of 2.53 inches, and a thickness of 0.192 inches, it is suited for general fastening applications in mechanical, structural, and maintenance work. Plumbers, electricians, HVAC technicians, and general tradespeople commonly stock USS flat washers for a wide range of bolted connections.\u003c\/p\u003e\n\u003cp\u003eThis washer is used wherever a 1-inch fastener requires a broad bearing surface to prevent pull-through or distribute clamping load across softer or oversized hole materials. Typical applications include equipment mounting, pipe hangers, structural connections, and general mechanical assembly in both residential and light commercial settings. The zinc-plated steel construction makes it appropriate for indoor and semi-protected outdoor environments where moderate corrosion resistance is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUSS standard dimensions provide wider load-bearing surface than SAE equivalents for the same screw size\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc-plated finish offers corrosion resistance in dry and semi-protected environments\u003c\/li\u003e\n  \u003cli\u003e1.055-inch inside diameter fits 1-inch nominal screw or bolt shafts with standard clearance\u003c\/li\u003e\n  \u003cli\u003e2.53-inch outside diameter distributes clamping force across a broad contact area\u003c\/li\u003e\n  \u003cli\u003e0.192-inch thickness provides consistent bearing surface under torque\u003c\/li\u003e\n  \u003cli\u003eMaterial Grade 2 steel suitable for general-purpose fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard USS flat washer for use with 1-inch nominal screws and bolts in general-purpose mechanical, plumbing, HVAC, and electrical fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using standard hand or power tools appropriate to the fastener being used. Ensure the mating surface is clean and flat before placing the washer to prevent uneven load distribution. Power down or de-energize equipment before servicing any fastened assembly.
