The partially threaded shank provides a smooth bearing surface through the joint, while the coarse UNC thread pattern seats securely in standard tapped holes or nuts. Manufactured to ASME B18.2.1 dimensional standards, this fastener delivers consistent head geometry and thread form for reliable torque and clamp load. The bright uncoated finish is suited for applications where surface treatments are applied post-installation or where base metal contact is preferred.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is commonly used in heavy-duty mechanical assemblies, structural steel connections, agricultural equipment, mining machinery, and general industrial fabrication where high tensile and proof strength are required. The 5\/8-11 UNC thread size is a standard coarse-pitch designation widely encountered in American mechanical systems. The 7-inch length under head accommodates thick stack assemblies or applications requiring extended grip length. Machinists, millwrights, and maintenance technicians are the typical installers for fasteners of this specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile strength for demanding load-bearing applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank maintains shank bearing surface through the joint for improved shear resistance\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC coarse thread standard ensures broad compatibility with American-standard hardware\u003c\/li\u003e\n  \u003cli\u003e7-inch length under head suits thick material stacks and extended grip applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish leaves base steel exposed for post-installation coating or bare metal contact\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B18.2.1 for consistent head dimensions and thread tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 5\/8-11 UNC hex nuts, washers, and tapped holes conforming to American inch-series fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a standard hex wrench or impact driver with the appropriate socket. Always power down or de-energize associated equipment before fastener replacement in mechanical assemblies. Use appropriate washers and torque procedures per the equipment manufacturer's specifications for Grade 8 fasteners. Inspect threads on both the screw and mating hardware for damage before installation to ensure full thread engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\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: UNC\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\u003eDimensional Standard\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\u003ePackage Quantity\u003c\/strong\u003e: 10 pieces\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: 99163\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692911427890,"sku":"99163","price":49.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29a6a55282421d58aee7ed9d3164140a.jpg?v=1788304852","url":"https:\/\/voomisupply.com\/products\/value-collection-99163-hex-head-cap-screw-5-8-11-x-7-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
