Measuring 5\/8-11 thread size with a 1.5-inch length under head, this fastener is fully threaded and finished with a clear zinc chromate coating for corrosion resistance. Grade 9 alloy steel provides greater tensile strength than standard Grade 5 or Grade 8 fasteners, making this screw well-suited for demanding mechanical and structural connections. Licensed tradespeople in mechanical, industrial, and heavy equipment fields rely on this grade for critical joint integrity.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is used in a range of industrial and commercial applications where high-strength inch-series fasteners are required. Typical install scenarios include equipment assembly, structural brackets, machinery mounting, and heavy-duty mechanical connections using standard 5\/8-11 UNC thread engagement. The clear zinc chromate finish provides moderate corrosion protection suitable for indoor and light outdoor environments. Sold in packages of 25, this part accommodates both single-unit and bulk fastening tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 alloy steel construction for high tensile strength beyond standard Grade 8\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread size with 1.5-inch length under head\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eClear zinc chromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for compatibility with standard UNC tooling\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 25 per unit sold\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 in any application requiring a 5\/8-11 UNC threaded fastener with a 1.5-inch grip length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or trades professional familiar with high-strength fastener requirements. Confirm mating thread condition and clean all contact surfaces before assembly. Apply appropriate torque per the applicable engineering specification or equipment manufacturer guidelines for Grade 9 fasteners at this diameter. Do not substitute Grade 9 fasteners in applications rated for lower grades without verifying joint design requirements.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Clear Zinc Chromate\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  \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: BOWMALLOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 36147\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":52042916757810,"sku":"36147","price":108.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ada62144e822bd4dc28cc05adb8edf89_69bc581b-2b93-47e1-82c5-9b6fc7e339bd.jpg?v=1790028717","url":"https:\/\/voomisupply.com\/products\/bowmalloy-36147-hex-head-cap-screw-5-8-11-x-1-5-in-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
