Built from 18-8 stainless steel and passivated for corrosion resistance, this bolt features a silicone O-ring under the head that compresses upon installation to create a fluid-tight seal. The 1\/2-13 UNC thread pattern and 3-inch length under the head make it suited for medium-duty structural and mechanical assemblies where both clamping strength and sealing performance are required. Plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals install this type of fastener in applications where standard hex bolts would allow fluid or gas migration past the bolt head.\u003c\/p\u003e\n\u003cp\u003eThis self sealing hex bolt is used in plumbing panels, HVAC equipment enclosures, fluid-handling assemblies, and industrial equipment where preventing moisture or liquid ingress around the fastener hole is critical. The passivated 18-8 stainless steel construction provides strong resistance to rust and corrosion, making it appropriate for both indoor wet environments and light outdoor exposure. Each package contains 5 bolts. Minimum order quantity is 1 package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone O-ring under the head creates a compression seal to prevent fluid or gas migration at the bolt hole\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction with passivation treatment for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread standard for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-inch length under the head accommodates medium-depth clamping and sealing applications\u003c\/li\u003e\n  \u003cli\u003eHex drive head compatible with standard hex wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 5 bolts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit self sealing hex bolt for any application requiring a 1\/2-13 UNC threaded fastener with an integrated O-ring seal, including equipment panels, fluid-handling enclosures, and mechanical assemblies that use standard inch-series hardware.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a standard hex wrench or socket sized for 1\/2-inch hex fasteners. De-energize or depressurize the assembly before installing or removing bolts in live fluid or electrical systems. Tighten fasteners evenly to compress the silicone O-ring uniformly without over-torquing, which can damage the O-ring and compromise the seal. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface Treatment\u003c\/strong\u003e: Passivated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Type\u003c\/strong\u003e: Silicone O-Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161600\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: ST1\/2-13X3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716928045362,"sku":"ST1\/2-13X3","price":87.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ade68a4c73aa075976d38581bf68465_98562b08-8b16-486b-a836-dbdca80546fa.jpg?v=1788533466","url":"https:\/\/voomisupply.com\/products\/value-collection-st1-2-13x3-self-sealing-hex-bolt","provider":"Voomi Supply","version":"1.0","type":"link"}
