It is partially threaded and left uncoated with a bright finish. Grade 8 steel provides high tensile strength for demanding structural and mechanical fastening applications. This screw meets ASME B18.2.1 standards, making it suitable for precision bolted assemblies where dimensional consistency is required. Machinists, millwrights, and maintenance technicians typically install this type of fastener in heavy-duty equipment, jigs, fixtures, and structural connections.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for industrial and commercial applications requiring a fine-thread fastener with high load-bearing capacity. The 5\/8-18 UNF thread pitch offers finer thread engagement than coarse-thread equivalents, which can be advantageous in applications where vibration resistance or precise preload control is needed. Typical uses include machine frames, heavy equipment assembly, and structural bolting in manufacturing environments.\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\u003e5\/8-18 UNF fine thread for improved vibration resistance and precise torque control\u003c\/li\u003e\n  \u003cli\u003e7-inch length under head accommodates thick material stacks and long-reach fastening needs\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a bearing surface for shear-load applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for use as-is or with additional corrosion protection as required by the application\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for dimensional compliance in precision assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use with 5\/8-18 UNF threaded holes or matching nuts in heavy-duty mechanical and structural assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 5\/16-inch hex key or an appropriate hex-drive socket. Always verify the mating thread is clean and undamaged before installation. Follow applicable torque specifications for Grade 8 fasteners as referenced in your project engineering documentation or applicable standards. De-energize and lock out any equipment before performing fastener installation or removal on live machinery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 7 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: 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: 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: 5\/16 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: 0.65 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: 451131BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693061505330,"sku":"451131BR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a451d2d1c730e51b883d45a5772a11e.jpg?v=1788306799","url":"https:\/\/voomisupply.com\/products\/value-collection-451131br-hex-head-cap-screw-5-8-18-x-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
