Manufactured from Grade 8 steel with a bright uncoated finish, this fastener delivers the tensile strength required for demanding load-bearing connections. The screw measures 8 inches under the head and features partial threading with a Unified National Coarse (UNC) thread form, conforming to ASME B18.2.1 dimensional standards. It is driven with a 9\/16-inch hex wrench or socket. Maintenance technicians, millwrights, and general contractors install this type of fastener where high-strength steel hardware is specified.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for mechanical equipment mounting, structural steel connections, and heavy-duty fabrication work where Grade 8 strength is required. The partially threaded shank provides a smooth bearing surface in the grip area, which is important in bolted joints where shear load is a factor. The UNC thread form is the standard choice for most carbon steel structural and mechanical fastening in North American applications. MOQ is 10 pieces; package quantity is 1 per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread form per ASME B18.2.1 standard\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head with partial threading for shear-capable bolted joints\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for indoor mechanical and structural use\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch hex key drive compatible with standard sockets and wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC hex head cap screw for use in any application requiring ASME B18.2.1 compliant Grade 8 fasteners with an 8-inch grip length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 9\/16-inch socket or open-end wrench; a torque wrench is recommended for any joint with a specified clamp load. Grade 8 fasteners should always be paired with Grade 8 or hardened nuts and washers to prevent thread stripping or bearing surface damage. Ensure mating threads are clean and free of debris before assembly. Follow applicable structural or mechanical codes for joint design and fastener torque requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Partially Threaded\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\u003eFinish Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\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: 0.25 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: 451077PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711803294002,"sku":"451077PR","price":79.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcdfc7558dadbbb1f2eab5a5c0ebb44b.jpg?v=1788479777","url":"https:\/\/voomisupply.com\/products\/value-collection-451077pr-hex-head-cap-screw-3-8-16x8-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
