It measures 5\/8-18 (UNF fine thread) with a 5-inch length under the head and features partial threading along the shank. The Bowma-Guard finish provides corrosion resistance suited to demanding service environments. This fastener is installed by millwrights, maintenance mechanics, and industrial tradespeople working on heavy equipment, structural connections, and precision machinery where Grade 9 tensile strength is specified.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is well-suited for use in industrial manufacturing, heavy-duty equipment assembly, and structural fastening scenarios that require fine-thread engagement and high clamping force. The partial threading is appropriate for applications where the unthreaded shank section provides a precise bearing surface or shear resistance in a clearance hole. It fits standard hex head tooling and is compatible with matching 5\/8-18 UNF nuts and tapped holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e5\/8-18 UNF fine thread for precise torque control and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e5-inch length under head accommodates thick assemblies and structural stacks\u003c\/li\u003e\n  \u003cli\u003ePartial threading provides a smooth shank bearing surface for shear-load applications\u003c\/li\u003e\n  \u003cli\u003eBowma-Guard finish offers corrosion protection in industrial environments\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 tapped holes or matching hex nuts in industrial and heavy-equipment fastening applications requiring Grade 9 strength.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanics or industrial tradespeople using a standard hex wrench or socket set sized for a 5\/8-inch hex head fastener. Always verify the mating tapped hole or nut is rated for the same thread class and tensile grade before torquing. De-energize and lock out any equipment before performing fastener replacement or service work. Follow applicable industry torque specifications for Grade 9 fasteners of this diameter as referenced in your equipment service documentation.\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 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\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 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bowma-Guard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.38 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\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: BOWMALLOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BOWMP36459\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":52047637545266,"sku":"BOWMP36459","price":146.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6918c367a9218c0ddcf20eb38115f7b7_836d3d69-1808-4440-a8d1-2c18a5cdeafc.jpg?v=1790032087","url":"https:\/\/voomisupply.com\/products\/bowmalloy-bowmp36459-hex-head-cap-screw-5-8-18-x-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
