This fastener features partial threading and conforms to ASME B18.2.1 standards, making it a reliable choice for high-strength bolted connections in demanding mechanical and structural assemblies. The UNF thread form at 1-1\/4-12 provides fine-thread engagement suitable for applications requiring greater tensile strength and vibration resistance than coarse-thread equivalents. It weighs 1.89 pounds and is driven with a 1-7\/8 inch hex key or wrench. Installers and maintenance technicians working in heavy equipment, industrial fabrication, or trade construction will find this fastener meets standard torque and load requirements for Grade 8 applications.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in high-load bolted joints across industrial, mechanical, and construction environments. Its partial threading allows for a smooth shank section between the head and the threaded portion, which is advantageous when the bolt passes through clearance holes before engaging a nut or tapped component. The 4-inch length under head accommodates thicker flanges, brackets, and structural members. Grade 8 steel provides significantly higher proof load and tensile strength compared to Grade 5 or lower designations, making this fastener appropriate for critical joint applications subject to vibration, shock, or sustained clamping loads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength and proof load capacity\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-12 UNF thread form for fine-thread engagement and improved vibration resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for clean passage through clearance holes\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — compatible with standard hardware pairing without coating interference\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003e1-7\/8 inch hex drive accommodates standard open-end, box-end, or socket wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.2.1 hex head cap screw for use with 1-1\/4-12 UNF nuts and tapped holes in high-strength bolted assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanical or maintenance technicians familiar with high-strength fastener torque procedures. De-energize and lock out any equipment before servicing fastened assemblies. Use a calibrated torque wrench and apply fastener torque values appropriate for Grade 8 steel and the joint material per applicable engineering specifications. Do not mix Grade 8 fasteners with lower-grade nuts, as mismatched hardware reduces joint integrity.\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: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: 1-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.89 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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: 451043BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723873583410,"sku":"451043BR","price":18.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_9d0ae58d-20e4-4ef4-b727-552cd8b64a22.jpg?v=1788609133","url":"https:\/\/voomisupply.com\/products\/value-collection-451043br-hex-cap-screw-1-1-4-12-x-4-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
