It features a 1-3\/4-5 UNC thread size with a 4-inch length under head, manufactured from Grade 8 steel with a bright uncoated finish. Conforming to ASME B18.2.1 standards, this fastener is designed for heavy-duty structural and mechanical assemblies where tensile strength and dimensional precision are critical. The hex head accepts a 2-5\/8-inch hex key, and full threading along the shank allows engagement from any point along the bolt length. Weighing 4.5 pounds, this is a substantial fastener suited for demanding industrial and commercial installations.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in heavy structural connections, machinery mounting, equipment fabrication, and industrial maintenance applications. Its Grade 8 rating makes it suitable for high-load assemblies in manufacturing, construction, and OEM equipment builds where standard-grade fasteners would be undersized for the required load. Licensed trades and skilled maintenance technicians working with structural steel frames, large mechanical assemblies, or industrial equipment commonly specify Grade 8 fasteners of this 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 strength\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank per ASME B18.2.1 dimensional standard\u003c\/li\u003e\n  \u003cli\u003e1-3\/4-5 UNC thread for compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with applied lubricants or thread-locking compounds\u003c\/li\u003e\n  \u003cli\u003e2-5\/8-inch hex key drive size accommodates heavy-duty wrenching\u003c\/li\u003e\n  \u003cli\u003e4-inch length under head provides substantial grip range for thick material stacks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock hex head cap screw for heavy-duty structural and mechanical assemblies requiring 1-3\/4-5 UNC Grade 8 fasteners conforming to ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified tradespeople or maintenance technicians familiar with high-strength fastener specifications and torque requirements. Always de-energize and lock out equipment before performing fastener replacement or installation in powered assemblies. Use appropriate calibrated torque tooling for Grade 8 fasteners; consult the equipment manufacturer or applicable structural standards for torque specifications specific to the assembly. Inspect mating threads and bearing surfaces for damage before installation and apply thread lubricant or compound as specified by the assembly procedure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/4-5 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: 2-5\/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\u003eWeight\u003c\/strong\u003e: 4.5 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: 451809BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701201469746,"sku":"451809BR","price":75.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_b8de97ea-b020-4209-b844-64449ea1ae4d.jpg?v=1788399752","url":"https:\/\/voomisupply.com\/products\/value-collection-451809br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
