Manufactured from Grade 8 steel with a bright uncoated finish, this fastener meets ASME B18.2.1 dimensional standards. The 1-1\/4-12 UNF thread profile provides fine-thread engagement, which delivers greater tensile strength and improved resistance to loosening under vibration compared to coarse-thread equivalents. At 2-1\/2 inches in length under the head and weighing 1.38 pounds per unit, this screw is suited for heavy-duty structural assemblies where precise clamp load is critical. Installation requires a 1-7\/8 inch hex key or wrench.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in heavy equipment, fabrication, maintenance, and repair applications where Grade 8 rated fasteners are specified. It is appropriate for static and dynamic load joints in steel structures, machinery frames, and mechanical assemblies. The fine UNF thread series makes it a common choice when high clamp force is needed in limited engagement depth situations. Machinists, millwrights, ironworkers, and maintenance mechanics typically work with fasteners of this grade and size.\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\/4-12 UNF fully threaded profile for maximum thread engagement along the full shaft length\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for dry or internally lubricated joint conditions\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003e1-7\/8 inch hex drive for use with standard open-end, box-end, or impact tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNF hex head cap screw compatible with 1-1\/4-12 threaded holes and nuts 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 trades following applicable industry torque standards for Grade 8 fasteners at this diameter and thread pitch. Always verify hole thread condition and clean threads before installation. Do not mix Grade 8 fasteners with lower-grade nuts or hardware. Apply thread lubricant only when specified, as lubrication significantly affects the torque-to-clamp-load relationship.\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\/4-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/2 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: Fully 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: 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: 1-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 1.38 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: 451040BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691361304882,"sku":"451040BR","price":34.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a7753d2f8de932129a118773e18b961.jpg?v=1788283812","url":"https:\/\/voomisupply.com\/products\/value-collection-451040br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
