Sized at 1-1\/4-12 UNF with a 3-1\/2 inch length under head, this fastener is manufactured from Grade 8 steel with a bright, uncoated finish. Grade 8 steel provides high tensile strength suitable for demanding bolted joint applications where lower-grade fasteners would be inadequate. This screw meets ASME B18.2.1 standards, making it a reliable choice for engineers, millwrights, and maintenance professionals working to specification.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in heavy equipment maintenance, machinery assembly, structural bolting, and industrial fabrication. The 1-1\/4-12 UNF thread pitch is a fine-thread profile, which provides greater thread engagement and resistance to loosening under vibration compared to coarse-thread equivalents. Full threading along the 3-1\/2 inch shank allows maximum engagement flexibility across varying material thicknesses. It is commonly installed by maintenance machinists, millwrights, and industrial mechanics working on presses, conveyors, gearboxes, and similar equipment.\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 strength\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank allows flexible engagement depth across joint thicknesses\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-12 UNF fine-thread profile for increased resistance to vibration loosening\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with separately applied coatings or in dry interior environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for consistent fit with standard hex nuts and hardened washers\u003c\/li\u003e\n  \u003cli\u003e1-7\/8 inch hex key size for use with standard industrial wrenching tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1-1\/4-12 UNF hex nuts and hardened flat washers conforming to ASME B18.2.2 and ASME F436 specifications, respectively, as applicable to Grade 8 bolted joint assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanics or millwrights familiar with high-strength bolted joint procedures. Always use a calibrated torque wrench and follow the applicable joint design torque specification for Grade 8 fasteners at this diameter and thread pitch. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. When used in critical structural or pressure-bearing applications, consult relevant codes such as AISC or applicable machinery OEM guidelines.\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: 3-1\/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: 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: 1-7\/8 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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.71 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: 451042BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693417300274,"sku":"451042BR","price":37.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_742a4c65-6f7d-49fe-a667-bf70b3cc30d3.jpg?v=1788312062","url":"https:\/\/voomisupply.com\/products\/value-collection-451042br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
