It carries a 1-1\/2-6 UNC thread size with an 8-inch length under head, and is manufactured from Grade 8 steel with a bright, uncoated finish. The partial threading leaves a smooth shank section between the head and the threaded portion, which reduces stress concentration in bolted joints and allows the shank to bear shear loads. At 4.87 pounds, this is a substantial fastener suited for industrial and heavy equipment assembly work where fastener integrity under load is critical.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in heavy industrial, construction, and OEM machinery applications where UNC coarse-thread fasteners are specified. The Grade 8 designation indicates a minimum tensile strength well above that of lower-grade fasteners, making it appropriate for structural connections, large equipment frames, press assemblies, and similar load-bearing installations. Machinists, millwrights, ironworkers, and field maintenance technicians working on heavy-duty equipment are the primary installers. The 2-1\/4-inch hex key drive size requires appropriate wrenching tooling for proper installation torque.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high-tensile-strength bolted connections\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-6 UNC coarse thread form for reliable engagement in standard inch-system tapped holes\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank reduces stress concentration and handles shear loading\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains dimensional accuracy per ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e2-1\/4-inch hex drive accommodates standard heavy-duty wrenching tools\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for interchangeability and quality assurance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application specifying a 1-1\/2-6 UNC hex head cap screw to ASME B18.2.1 dimensional standards in inch-measurement systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, machinist, or maintenance technician using a properly rated torque wrench and a 2-1\/4-inch hex socket or open-end wrench. Always verify that the mating tapped hole or nut is rated for Grade 8 loading before assembly, as mismatched grades can cause joint failure. Inspect threads for damage before installation and do not apply lubricants or thread-locking compounds unless specified by the equipment manufacturer, as these alter the torque-tension relationship. Follow applicable ASME or OEM torque specifications for the joint design.\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: 8 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\u003eWeight\u003c\/strong\u003e: 4.87 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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\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: 451069BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694296138034,"sku":"451069BR","price":75.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/faba80ea98c7340f22cda4247c314449.jpg?v=1788322751","url":"https:\/\/voomisupply.com\/products\/value-collection-451069br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
