It measures 1-1\/2-6 thread size by 16 inches in length under head, with a Unified National Coarse (UNC) thread form and partial threading along the shank. Manufactured from Grade 8 steel with a bright uncoated finish, this fastener meets ASME B18.2.1 dimensional standards. At 8.92 pounds, this is a large-format fastener intended for industrial assemblies, heavy equipment, and structural connections where high tensile and proof load strength are required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for industrial maintenance, heavy equipment fabrication, structural steel assembly, and general mechanical applications where Grade 8 load ratings are specified. The partially threaded shank provides a smooth bearing surface that resists shear forces in bolted joints. A 2-1\/4 inch hex key size accommodates standard heavy-duty impact or torque wrenches. Licensed machinists, millwrights, ironworkers, and industrial mechanics are the primary installers of fasteners at this size class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets high tensile strength requirements for structural and heavy mechanical fastening\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides shear resistance and proper bolt grip in thick-section joints\u003c\/li\u003e\n  \u003cli\u003eASME B18.2.1 compliance ensures dimensional accuracy and interchangeability with standard hardware\u003c\/li\u003e\n  \u003cli\u003eUNC thread form for compatibility with standard inch-system nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with applied lubricants or customer-specified coatings\u003c\/li\u003e\n  \u003cli\u003e2-1\/4 inch hex drive accommodates standard heavy industrial wrenches and impact tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.2.1 inch-series hex head cap screw for use with any 1-1\/2-6 UNC threaded nut, heavy hex nut, or tapped hole meeting the same thread standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanics or ironworkers familiar with torque requirements for Grade 8 fasteners at this thread size. Always verify thread engagement depth and mating nut or tapped-hole grade before assembly. Apply a suitable thread lubricant or anti-seize compound as required by the application specification. Use properly rated torque equipment to achieve the specified clamp load without yielding the fastener.\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\/2-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eHex Key Size\u003c\/strong\u003e: 2-1\/4 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: 8.92 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: 451788BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698356126002,"sku":"451788BR","price":58.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_d5757dfe-9843-4987-9575-40919ce8ed0c.jpg?v=1788361607","url":"https:\/\/voomisupply.com\/products\/value-collection-451788br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
