Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this washer provides corrosion resistance and load distribution across a wide range of mechanical and structural applications. The inside diameter measures 3\/8 inches, the outside diameter measures 7\/8 inches, and the thickness is 5\/64 inches. Electricians, plumbers, HVAC technicians, and general tradespeople install flat washers like this one to distribute clamping load, protect mating surfaces, and reduce the risk of fastener pull-through in both metal and wood substrates.\u003c\/p\u003e\u003cp\u003eThis USS-pattern flat washer follows inch-system dimensional standards, making it suited for residential and light commercial construction, mechanical equipment mounting, and utility installations. The larger outside diameter relative to the screw size is characteristic of USS series washers, which are preferred when broader load distribution is needed. The zinc yellow dichromate coating provides a baseline level of corrosion resistance appropriate for interior and protected exterior environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction for reliable strength in structural fastener applications\u003c\/li\u003e\n\u003cli\u003eZinc yellow dichromate finish for corrosion resistance in interior and protected settings\u003c\/li\u003e\n\u003cli\u003eUSS series pattern delivers wider load distribution compared to SAE flat washers\u003c\/li\u003e\n\u003cli\u003eInside diameter of 3\/8 inches fits 5\/16 inch screw shanks with appropriate clearance\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 7\/8 inches provides broad bearing surface to protect mating materials\u003c\/li\u003e\n\u003cli\u003eInch-system dimensions for direct use with standard imperial fastener hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and general-purpose replacement flat washer for use with 5\/16 inch screw fasteners in residential, commercial, and mechanical installations following inch-system dimensional standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using standard hand tools; ensure the washer seats flush against the mating surface before torquing the fastener. Power down or de-energize any electrical or mechanical system before performing fastener work in live panels or equipment enclosures. Follow applicable codes such as NEC or IFGC when installing fasteners in code-governed systems. Do not substitute a USS washer for an SAE washer in applications where outside diameter clearance is restricted.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: USS Flat Washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161807\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 39751\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706142261554,"sku":"39751","price":60.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34473f88f3285115b8cb5a77c999941b.jpg?v=1788432896","url":"https:\/\/voomisupply.com\/products\/value-collection-39751-uss-flat-washer-5-16-inch-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
