Manufactured from Grade 8 steel with a bright uncoated finish, this fastener delivers the elevated tensile strength required for demanding structural and equipment-mounting work. The screw measures 2-4\/2 inches in thread size and 15 inches in length under head, with partial threading along the shank. It conforms to ASME B18.2.1, the standard governing inch-series hex cap screws, ensuring consistent dimensional accuracy and mechanical performance across critical joints.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy industrial assemblies, large machinery, structural steel connections, and fabrication work where a Grade 8 fastener is specified. The partially threaded shank provides a bearing surface that resists shear loads in bolted connections. At 16.5 pounds per unit, this is a large-format fastener typically specified by mechanical contractors, industrial maintenance technicians, and structural fabricators working with thick-gauge steel components or heavy equipment frames.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength for critical bolted joints\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear resistance and bolt alignment in thick-material applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for environments where coatings are not required or where additional plating will be applied\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for dimensional accuracy and mechanical property compliance\u003c\/li\u003e\n  \u003cli\u003eUNC thread standard ensures broad compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eHex key size of 3 inches accommodates heavy-duty drive tooling appropriate for large-diameter fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard UNC inch-series hex nuts and tapped holes in Grade 8 or compatible steel assemblies conforming to ASME B18.2.1 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanical or structural technicians using calibrated torque equipment rated for large-diameter Grade 8 fasteners. Always verify that the mating nut or tapped hole thread class and material grade are compatible before assembly. Follow applicable torque specifications from a recognized engineering reference or project specification, as none are supplied with this fastener. Inspect threads for damage before installation and ensure the joint surfaces are clean and free of debris.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-4\/2 inches UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\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\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 3 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\u003eWeight\u003c\/strong\u003e: 16.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 451893BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696414916914,"sku":"451893BR","price":108.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d6b134451e3cac8bf86f22cce6d77ff.jpg?v=1788342414","url":"https:\/\/voomisupply.com\/products\/value-collection-451893br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
