This fastener is partially threaded and conforms to ASME B18.2.1 dimensional standards. With a thread size of 1-1\/2-12 UNF and a length under head of 13 inches, it is engineered for high-strength bolted connections that require fine-thread engagement. The 2-1\/4-inch hex key size accommodates standard industrial wrenching. At 7.42 pounds, this is a substantial fastener suited for structural and mechanical assembly work performed by maintenance mechanics, millwrights, and industrial technicians.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in heavy industrial and mechanical applications where high tensile strength and fine-thread precision are required. Typical install scenarios include large machinery frames, structural steel connections, hydraulic equipment mounts, and heavy fabrication assemblies. The partially threaded shank provides a bearing surface in the bolt hole, which is important in shear-load applications. Grade 8 steel provides significantly higher proof load and tensile strength than Grade 5 fasteners, making this appropriate for demanding service environments.\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 capacity\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-12 UNF fine thread for precise torque control and reduced loosening risk\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank designed to handle shear and bearing loads\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for use with aftermarket coatings or as-is in dry indoor environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003e2-1\/4-inch hex drive accommodates standard industrial box-end wrenches and impact sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in inch-series bolted assemblies requiring a 1-1\/2-12 UNF thread pattern and 13-inch grip length, consistent with ASME B18.2.1 hex head cap screw specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanics or millwrights familiar with high-strength fastener procedures. Always verify mating thread condition and hole alignment before driving. Apply thread lubricant or anti-seize only if specified by the equipment manufacturer, as lubrication affects torque-tension relationships. Use calibrated torque equipment appropriate for Grade 8 fasteners of this size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.42 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1\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: 451797BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721798353202,"sku":"451797BR","price":51.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bcc74ad2a79c36f7fc45c93d0ccb0149.jpg?v=1788581042","url":"https:\/\/voomisupply.com\/products\/value-collection-451797br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
