It features partial threading and a Bowma-Guard zinc-plated clear chromate finish that resists corrosion in demanding service environments. This fastener is built to inch-system specifications and is suited for high-strength bolted joint applications where a fine-thread pattern and superior tensile strength are required. Maintenance technicians, millwrights, and assembly mechanics working on heavy equipment, structural assemblies, or industrial machinery are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for industrial and commercial applications requiring a fine-thread, high-strength fastener. The 5\/8-18 UNF thread pitch offers better thread engagement and vibration resistance compared to coarse-thread equivalents, making it a common choice in drivetrain assemblies, bracket mounting, and load-bearing mechanical connections. The partially threaded shank provides a clean bearing surface in the grip area, which is important in shear-loaded joint configurations.\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 form for improved torque control and vibration resistance\u003c\/li\u003e\n  \u003cli\u003ePartial threading preserves a full shank grip area for shear-loaded joints\u003c\/li\u003e\n  \u003cli\u003eBowma-Guard zinc-plated clear chromate finish for corrosion protection\u003c\/li\u003e\n  \u003cli\u003eInch-system dimensions conforming to standard hex head cap screw geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in inch-system bolted assemblies requiring a 5\/8-18 UNF fine-thread hex head cap screw.

Always consult the equipment manufacturer's torque table for the correct installation torque for this thread size and grade. Ensure mating threaded holes or nuts are clean and free of debris before assembly. Do not mix Grade 9 fasteners with lower-grade nuts or threaded inserts that are not rated for the corresponding clamp load.\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: 5-1\/2 inches\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\/Coating\u003c\/strong\u003e: Bowma-Guard Zinc-Plated Clear Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\u003eWeight\u003c\/strong\u003e: 0.01 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: BOWMALLOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BOW36460\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":52031182799154,"sku":"BOW36460","price":170.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6918c367a9218c0ddcf20eb38115f7b7_e14fd102-01d4-459c-ae0b-f18a5807ed5b.jpg?v=1790019878","url":"https:\/\/voomisupply.com\/products\/bowmalloy-bow36460-hex-head-cap-screw-5-8-18-x-5-1-2-in-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
