Threaded at 5\/8-11 (UNC) with a right-hand thread direction, this nut features a Bowma-Guard cadmium waxed finish that provides corrosion and wear protection. At 0.542 inches in height with a 15\/16-inch (0.9375 inches) width across flats, it fits standard 15\/16-inch hex tooling. Grade 9 steel offers higher proof load and tensile strength than Grade 5 or Grade 8, making it a go-to choice for demanding structural, mechanical, and industrial fastening tasks handled by millwrights, maintenance technicians, and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for heavy-duty bolted assemblies in industrial machinery, structural steel, agricultural equipment, and commercial vehicle applications where fasteners are exposed to dynamic loads or sustained vibration. The 5\/8-11 UNC thread size is among the most common inch-series heavy fastener threads, making this nut a practical stock item for field service kits and shop inventory. Sold in a package quantity of 50, it is appropriate for both single-repair use and batch assembly work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 steel construction for superior proof load and tensile strength versus Grade 5 and Grade 8 nuts\u003c\/li\u003e\n  \u003cli\u003eBowma-Guard cadmium waxed finish provides corrosion resistance and lubricity for consistent torque application\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC right-hand thread for compatibility with standard inch-series fastener systems\u003c\/li\u003e\n  \u003cli\u003e15\/16-inch width across flats fits standard hex sockets and open-end wrenches\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 50 supports both repair and production assembly needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/8-11 UNC inch-series threaded bolts and studs in heavy-duty mechanical and structural assemblies requiring Grade 9 fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, mechanical technicians, or structural tradespeople using a 15\/16-inch socket or open-end wrench. Always ensure the mating bolt or stud is also rated to Grade 9 or equivalent to avoid mismatched fastener strength. Power down or de-energize any equipment before working on bolted assemblies on live machinery. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for the 5\/8-11 thread size and Grade 9 material grade.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Lock Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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 Cadmium Waxed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.542 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 15\/16 inches (0.9375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161716\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\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: BOW36786\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51964817473842,"sku":"BOW36786","price":198.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eeb2e95729df849ce5ddbfe2a77ad730_0c42fb41-6c0a-495c-80b6-b4a4b4b96b1a.jpg?v=1789949346","url":"https:\/\/voomisupply.com\/products\/bowmalloy-bow36786-hex-lock-nut-5-8-11-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
