This fastener uses a Unified National Coarse (UNC) thread standard and measures 3 inches under the head with a 3\/4 inch hex drive. Grade 316 stainless steel provides elevated corrosion resistance compared to 304-series alloys, making it a preferred choice in chemically aggressive or moisture-heavy environments. Licensed plumbers, pipefitters, HVAC technicians, and general mechanical contractors reach for 316 stainless hardware when installations demand long-term resistance to oxidation, chlorides, and industrial chemicals.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in plumbing systems, HVAC equipment mounting, pool and spa mechanical installations, marine environments, and chemical processing applications. The 1\/2-13 UNC thread pattern is a standard inch-series size compatible with common tapped holes and hex nuts in trade and industrial assemblies. It is equally applicable in both new construction and maintenance or repair work where corrosion-resistant fasteners are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for superior chloride and chemical corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread standard for broad compatibility with inch-series hardware\u003c\/li\u003e\n  \u003cli\u003e3 inch length under head suits medium-to-deep clamping applications\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch hex drive accepts standard wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eFull stainless construction eliminates galvanic corrosion risk when paired with stainless nuts and washers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC hex head cap screw for use with inch-series tapped holes, hex nuts, and flanged assemblies in trade and industrial applications requiring Grade 316 stainless steel fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified tradespeople using standard open-end, box-end, or socket wrenches sized for a 3\/4 inch hex. Verify that mating threads, nuts, and washers are also stainless steel to prevent galvanic corrosion in wet or chemically exposed environments. Fastener specifications for structural or pressure-boundary connections may be governed by applicable mechanical or plumbing codes — consult project documentation before substituting hardware grades.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 204074B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695164752178,"sku":"204074B","price":4572.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76d6e0f82b2c286edf60a11a3bf4f4ae.jpg?v=1788331959","url":"https:\/\/voomisupply.com\/products\/value-collection-204074b-hex-head-cap-screw-1-2-13-x-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
