It measures 0.308 inches inside diameter, 0.767 inches outside diameter, and 0.131 inches thick. The countersunk profile seats flush-head fasteners — such as flat-head screws and bolts — allowing the fastener to sit level with or below the mating surface. The 18-8 stainless steel construction provides corrosion resistance suitable for wet, outdoor, and light chemical environments. This washer is used by plumbers, pipefitters, millwrights, and general maintenance technicians wherever a clean, flush fastener installation is required.\u003c\/p\u003e\n\u003cp\u003eThis countersunk washer is suited for residential and commercial fastening applications where flush-mount hardware is specified. Common uses include panel mounting, sheet metal assembly, cabinetry, marine hardware, and equipment enclosures. The 18-8 stainless material makes it appropriate for environments with moisture exposure or where ferrous hardware is not acceptable. It pairs with flat-head machine screws and similar countersunk fasteners in the corresponding diameter range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction for corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eStandard countersunk profile seats flat-head fasteners flush with the work surface\u003c\/li\u003e\n  \u003cli\u003e0.308 inches inside diameter fits standard screw sizes in the corresponding range\u003c\/li\u003e\n  \u003cli\u003e0.767 inches outside diameter provides adequate bearing surface area\u003c\/li\u003e\n  \u003cli\u003e0.131 inches thickness for consistent seating depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard countersunk washer for use with flat-head fasteners requiring a flush seating surface across general mechanical, plumbing, and equipment assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by general maintenance technicians, pipefitters, or assembly personnel using standard hand tools. Ensure the mating surface countersink angle matches the washer profile before installation to achieve a proper flush seat. De-energize and isolate any equipment before disassembly or fastener replacement. Stainless steel hardware should be installed with anti-seize compound when thread galling is a concern.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Standard Countersunk\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: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.308 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.767 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161832\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: 3SWFI904\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707807891762,"sku":"3SWFI904","price":1046.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0ac16afe68be327fd059993b5fbb05b.jpg?v=1788442292","url":"https:\/\/voomisupply.com\/products\/value-collection-3swfi904-countersunk-washer-ss-18-8","provider":"Voomi Supply","version":"1.0","type":"link"}
