Grade 8 is a high-strength designation suited for demanding mechanical and structural fastening applications where tensile strength and resistance to shear stress are critical. The screw is partially threaded and left uncoated, conforming to ASME B18.2.1 dimensional standards. It is installed using a standard hex wrench or socket. Maintenance mechanics, millwrights, and field service technicians routinely spec this fastener size for heavy-duty equipment assembly and repair work.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for general industrial and mechanical fastening in both shop and field environments. The 5\/8-18 UNF thread pitch is a fine-thread specification, which provides greater thread engagement strength and better resistance to loosening under vibration compared to coarse-thread alternatives of the same diameter. The partial threading leaves a shank section below the head, which is common in joint applications where shear loading is a primary design consideration. Sold in a package quantity of 25.\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 form for increased thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a bearing surface for shear-loaded joints\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no plating or treatment that could affect dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standard for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 25 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-specification hex head cap screw for use in any application requiring a 5\/8-18 UNF Grade 8 partially threaded fastener per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a properly sized hex socket or open-end wrench rated for Grade 8 fastener torque requirements. Follow the equipment manufacturer or applicable engineering specification for target torque values, as proper clamp load is critical for joint integrity. Ensure mating threads are clean and free of debris before installation. Do not mix inch and metric fasteners in the same joint assembly.\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: 2.5 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: Uncoated\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\u003ePackage Quantity\u003c\/strong\u003e: 25\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: C703413\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701568176434,"sku":"C703413","price":57.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c28eb2d4d9e32575ba55f00249d822d4_1404f3ba-58ea-4794-945e-ac7f17f38114.jpg?v=1788401695","url":"https:\/\/voomisupply.com\/products\/value-collection-c703413-hex-head-cap-screw-5-8-18","provider":"Voomi Supply","version":"1.0","type":"link"}
