Grade 8 steel provides high tensile strength suited for demanding fastener applications where a standard or lower-grade screw would not hold up. The 1-3\/8-12 designation indicates a 1-3\/8 inch nominal diameter with 12 threads per inch on a Unified Fine thread form. This screw is manufactured to ASME B18.2.1 dimensional standards, making it a consistent, spec-compliant choice for mechanical assemblies, structural connections, and heavy equipment maintenance.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in industrial, commercial, and heavy-duty mechanical applications where high-strength fasteners are required. Partially threaded shanks are preferred when a smooth bearing surface under the head is needed to resist shear loads or when clamping two components without thread engagement through the full grip length. Typical installation scenarios include machine frames, structural steel connections, large equipment assemblies, and similar high-load joint applications. The bright uncoated finish is suitable for indoor or protected environments where corrosion exposure is limited.\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\u003e1-3\/8-12 UNF thread form — fine pitch for precise torque control and reduced loosening under vibration\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a smooth grip section for shear-resistant joints\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B18.2.1 for consistent dimensional conformance\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect thread fit or dimensional tolerance\u003c\/li\u003e\n  \u003cli\u003e2-1\/16 inch hex key size for standard hex drive tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in inch-series fastener applications requiring a 1-3\/8-12 UNF Grade 8 hex head cap screw with a 5-1\/2 inch length under head and ASME B18.2.1 compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, mechanical contractors, or maintenance technicians using a 2-1\/16 inch hex wrench or socket. De-energize, depressurize, or otherwise lock out any equipment before fastener service per applicable OSHA lockout\/tagout procedures. Grade 8 fasteners should be torqued to values specified by the equipment manufacturer or applicable engineering standards — do not substitute a lower-grade fastener in a Grade 8-specified joint. Inspect threads for damage before installation; do not install a fastener with crossed or damaged threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/8-12\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: 5-1\/2 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: 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\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 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: 451714BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710635606322,"sku":"451714BR","price":54.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85a2ea29f0183718b0628bc7e1557bc3.jpg?v=1788468950","url":"https:\/\/voomisupply.com\/products\/value-collection-451714br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
