Grade 8 steel delivers high tensile strength suitable for demanding bolted joints in heavy equipment, structural assemblies, and industrial machinery. The partially threaded shank provides a bearing surface that resists shear loads at the joint interface. This fastener meets ASME B18.2.1 dimensional standards and is installed using a 2-1\/4 inch hex key or matching socket. Machinists, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy-duty bolted connections in industrial, agricultural, construction, and OEM equipment applications where a fine-thread UNF pattern is specified. The 1-1\/2-12 thread pitch provides precise clamping adjustment and superior resistance to loosening under vibration compared to coarse-thread equivalents. The 8-inch length under head accommodates thick flanges, structural members, or stacked components requiring a long grip length. It is sold individually, making it practical for repair and replacement jobs as well as prototype builds.\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\/2-12 UNF fine thread for precise clamping and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e8 inches length under head for thick-grip bolted joint applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a shear-bearing surface at the joint\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — compatible with field plating or coating as needed\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standard\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 in any application specifying a 1-1\/2-12 UNF Grade 8 fastener with an 8-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or qualified maintenance personnel using a 2-1\/4 inch hex socket or wrench. De-energize all equipment and relieve system pressure before disassembling bolted joints. Apply thread lubricant or anti-seize as required by the joint specification; always follow the equipment manufacturer torque table for the fastener grade and size. Inspect threads for damage before installation and discard any fastener with deformed or corroded threads.\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\/2-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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 Coating\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\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\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: 451097BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692647481650,"sku":"451097BR","price":78.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b2f85209760fff4f51d47c1616037ab.jpg?v=1788300541","url":"https:\/\/voomisupply.com\/products\/value-collection-451097br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
