Manufactured from Grade 316 stainless steel, this washer provides strong corrosion resistance in wet, marine, and chemical-exposure environments. It measures 0.5 inches inner diameter, 1.25 inches outer diameter, and 0.083 inches thick, conforming to USS (United States Standard) dimensional specifications. The larger outer diameter of USS washers distributes clamping load across a broader surface area compared to SAE washers, reducing fastener pull-through in softer substrates. Plumbers, pipefitters, marine contractors, and industrial maintenance technicians commonly use this washer in corrosive or outdoor service applications.\u003c\/p\u003e\n\u003cp\u003eThis washer is suited for residential and commercial plumbing, marine hardware assemblies, outdoor structural connections, pool and spa equipment installations, and any application where chloride or moisture exposure would corrode standard carbon or 18-8 stainless hardware. Grade 316 stainless steel contains molybdenum, which increases resistance to pitting corrosion from chlorides compared to Grade 304. It follows USS dimensional standards, making it a standard drop-in fit wherever 7\/16 inch USS flat washers are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for superior corrosion resistance in marine and chemical environments\u003c\/li\u003e\n  \u003cli\u003eUSS standard dimensions provide broader load distribution compared to SAE flat washers\u003c\/li\u003e\n  \u003cli\u003e0.5 inch inner diameter clears 7\/16 inch screw shanks with standard USS allowance\u003c\/li\u003e\n  \u003cli\u003e1.25 inch outer diameter spreads clamping load to reduce fastener pull-through\u003c\/li\u003e\n  \u003cli\u003e0.083 inch thickness meets USS specification for this screw size\u003c\/li\u003e\n  \u003cli\u003eMolybdenum-alloyed 316 SS resists pitting from chlorides, saltwater, and pool chemicals\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 7\/16 inch screws and bolts in inch-measurement fastener assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using standard hand tools appropriate to the fastener type. Ensure mating fasteners are also Grade 316 stainless to prevent galvanic corrosion between dissimilar metals. Follow applicable mechanical and plumbing codes when used in structural or pressure-boundary connections. Do not over-torque fasteners, as stainless steel hardware is susceptible to galling without proper lubrication.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: USS Flat Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.083 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161807\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 30803\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694955069746,"sku":"30803","price":187.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aec5d73af1bf58042d34831791639e9a.jpg?v=1788329957","url":"https:\/\/voomisupply.com\/products\/value-collection-30803-uss-flat-washer-7-16-in-grade-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
