It carries a 1-3\/4-5 UNC thread size with a 5-inch length under head, manufactured from Grade 8 steel with a bright uncoated finish. Grade 8 steel is a high-strength fastener material rated for demanding structural and mechanical assembly work. This screw conforms to ASME B18.2.1 dimensional standards and is driven with a 2-5\/8 inch hex key. Machinists, millwrights, and maintenance technicians typically install this type of fastener in heavy equipment, structural steel assemblies, and industrial machinery where high tensile strength is required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for industrial and commercial applications requiring large-diameter, high-strength UNC fasteners. Full threading along the 5-inch shank length provides maximum thread engagement across the entire grip length, which is common in through-bolt configurations and thick-plate assemblies. It is applicable wherever ASME B18.2.1 compliant hex head fasteners are specified on engineering drawings or maintenance documentation.\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 maximizes thread engagement throughout the grip length\u003c\/li\u003e\n  \u003cli\u003e1-3\/4-5 UNC thread form for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for applications where surface coating is not required or specified\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standard\u003c\/li\u003e\n  \u003cli\u003e2-5\/8 inch hex key drive for use with standard heavy-duty wrenching tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for industrial and mechanical assemblies requiring 1-3\/4-5 UNC fully threaded hex head cap screws conforming to ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, mechanic, or maintenance technician familiar with large-diameter fastener procedures. De-energize and lock out all relevant equipment before removing or installing structural fasteners. Use a calibrated torque wrench rated for large-diameter applications and follow the torque specifications provided in the equipment service documentation. Inspect threads on both the fastener and mating tapped hole for damage or contamination before installation.\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: 5 inches\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\u003eThread Standard\u003c\/strong\u003e: UNC\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: 5.2 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: 451815BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692698042674,"sku":"451815BR","price":85.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_f5f3a233-0828-4514-91c3-faa4ded86a09.jpg?v=1788301372","url":"https:\/\/voomisupply.com\/products\/value-collection-451815br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
