It features a 5\/8-18 UNF right-hand thread with a Bowma-Guard cadmium waxed finish that provides corrosion resistance in demanding environments. The nut measures 0.542 inches in height with a width across flats of 15\/16 inches (0.9375 inches). At 0.01 pounds per unit, it is sold in packages of 50. This fastener is appropriate for mechanical assemblies, industrial equipment, and heavy-duty structural connections requiring a prevailing-torque locking mechanism.\u003c\/p\u003e\n\u003cp\u003eThe BOW36801 is suited for industrial and commercial applications where high-strength, fine-thread fasteners are specified. Grade 9 steel construction makes it appropriate for demanding mechanical and structural assemblies subject to dynamic loads, shock, or continuous vibration. Typical install scenarios include heavy equipment, agricultural machinery, automotive components, and industrial fabrication where UNF thread engagement and a locking element are required. The Bowma-Guard finish adds a layer of protection against corrosion in exposed or moderately harsh service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 steel construction for high tensile strength in demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003e5\/8-18 UNF right-hand thread for precise fine-pitch engagement\u003c\/li\u003e\n  \u003cli\u003eBowma-Guard cadmium waxed finish provides corrosion protection\u003c\/li\u003e\n  \u003cli\u003eWidth across flats of 15\/16 inches fits standard hex tooling\u003c\/li\u003e\n  \u003cli\u003ePrevailing-torque hex lock nut design resists loosening under vibration\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 50 for jobsite or shop stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-strength replacement or new-installation hex lock nut for 5\/8-18 UNF threaded fastener applications requiring Grade 9 steel with a locking feature.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright familiar with high-strength fastener specifications. Verify thread engagement length and mating bolt grade before torquing. Always use appropriately rated tools and follow the applicable equipment or assembly torque specifications provided by the equipment manufacturer. Inspect the locking element and finish for damage before installation and do not reuse lock nuts that show signs of deformation or wear.\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\/8-18\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: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\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\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161716\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: BOW36801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51971499426098,"sku":"BOW36801","price":176.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eeb2e95729df849ce5ddbfe2a77ad730_330a4ef7-4a58-4bcf-8cf1-9253dd3494a6.jpg?v=1789957915","url":"https:\/\/voomisupply.com\/products\/bowmalloy-bow36801-hex-lock-nut-5-8-18-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
