With a 1-1\/4-12 UNF thread and a 4-1\/2 inch length under head, this fastener delivers the clamping force required in heavy-duty bolted joints. The partial threading allows for precise load distribution along the shank. Finished bright and uncoated, it is suited for dry or controlled indoor environments. Manufactured to ASME B18.2.1 standards, it meets dimensional requirements expected by maintenance, millwright, and industrial trade professionals.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in applications where fine-thread engagement and high tensile strength are required, including machinery mounts, structural steel connections, hydraulic equipment, and heavy equipment repair. The 1-1\/4-12 UNF thread designation indicates a fine-thread series, which provides greater resistance to loosening under vibration compared to coarse-thread equivalents. Suitable for use with standard Grade 8 hex nuts and hardened washers in inch-series assemblies.\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\u003e1-1\/4-12 UNF fine thread for improved vibration resistance and precise torque control\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows load to bear along the unthreaded body\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for dry service environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standard\u003c\/li\u003e\n  \u003cli\u003e1-7\/8 inch hex key size for use with standard open-end, box, or impact wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in inch-series bolted assemblies requiring a 1-1\/4-12 UNF Grade 8 hex head cap screw per ASME B18.2.1.

Always confirm mating thread class and verify the joint design specifies Grade 8 fasteners before installation. Do not substitute uncoated fasteners in corrosive or outdoor environments without verifying suitability. Follow applicable industry torque guidelines for the joint category and fastener grade.\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: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\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: 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\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: 2.06 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: 451044BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696675160370,"sku":"451044BR","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6abe6b1ba468a521830a183d9941708c.jpg?v=1788345083","url":"https:\/\/voomisupply.com\/products\/value-collection-451044br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
