It carries a 1-1\/2-6 UNC thread size with a 9-inch length under head and is partially threaded, allowing the unthreaded shank to bear shear loads in close-tolerance applications. Manufactured from Grade 8 steel with a bright uncoated finish, this fastener meets ASME B18.2.1 dimensional standards. It weighs 5.33 pounds and requires a 2-1\/4-inch hex key or wrench for installation. Machinists, millwrights, structural ironworkers, and maintenance mechanics use this size in heavy fabrication, press frames, equipment mounting, and similar demanding applications.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for high-load bolted joints in industrial machinery, structural steel connections, and heavy equipment assemblies where Grade 8 tensile strength is required. The 1-1\/2-6 UNC thread form is a coarse-pitch inch-series thread common in large-diameter structural fastener applications. The partially threaded shank provides a grip length that resists lateral forces in shear-critical joints. This size is typically specified on fabrication drawings and equipment service manuals for mainframe, base plate, and bearing housing connections.\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 mechanical fastening\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-6 UNC coarse thread for reliable engagement in standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a bearing surface to resist shear loads\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for dry indoor applications or where secondary coating will be applied\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standard for consistent fit and interchangeability\u003c\/li\u003e\n  \u003cli\u003e2-1\/4-inch hex drive accommodates standard large-capacity impact wrenches and torque wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use with 1-1\/2-6 UNC tapped holes or heavy hex nuts in structural, industrial, and mechanical assemblies requiring Grade 8 fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified millwrights, ironworkers, or mechanical maintenance technicians familiar with high-strength fastener torque requirements. De-energize and lock out all equipment before replacing structural fasteners in machinery. Use a calibrated torque wrench to achieve the specified clamp load per the equipment manufacturer or applicable engineering specification. Do not impact-drive Grade 8 fasteners to final torque without verifying proper seating and thread engagement.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 9 inches\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\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensional Standard\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: 5.33 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: 451070BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722588750130,"sku":"451070BR","price":58.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c020e0410c6af2ab8fb956d3b20f28e9.jpg?v=1788593210","url":"https:\/\/voomisupply.com\/products\/value-collection-451070br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
