Threaded at 1-1\/8-7 inch right-hand thread, this nut measures 31\/32 inches high and 1-11\/16 inches across the flats. The Bowma-Guard finish provides corrosion resistance suited to demanding service environments. This fastener is installed by industrial maintenance technicians, millwrights, and mechanical contractors working on heavy equipment, structural assemblies, and high-load mechanical connections.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is appropriate for use in industrial, commercial, and heavy-duty mechanical applications where a standard hex nut is insufficient and a locking fastener is required. The 1-1\/8-7 thread size positions this nut for large-diameter bolted joints commonly found in machinery, structural steel, and equipment mounting. Sold in packs of 10, it suits both single-use repair jobs and small-volume stocking needs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 steel construction for high tensile strength and fatigue resistance\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-7 inch right-hand thread for compatibility with standard large-diameter fastener systems\u003c\/li\u003e\n  \u003cli\u003eBowma-Guard finish provides corrosion protection in harsh service environments\u003c\/li\u003e\n  \u003cli\u003e31\/32 inch height and 1-11\/16 inch width across flats for standard wrench engagement\u003c\/li\u003e\n  \u003cli\u003eHex lock nut design resists loosening under vibration and dynamic loads\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 10 for convenience on single repairs or light stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or service hex lock nut for 1-1\/8-7 inch right-hand threaded bolts and studs in industrial and heavy-duty mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of large-diameter hex lock nuts typically requires a properly sized open-end or box wrench and should follow torque specifications outlined in the equipment service manual or applicable ASME standards. Ensure mating bolt threads are clean and undamaged before installation. Do not exceed the rated torque for the fastener grade. Lock nut engagement should be verified after initial installation and re-checked following any significant load or vibration event.\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: 1-1\/8-7 inch\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\u003eHeight\u003c\/strong\u003e: 31\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-11\/16 inches\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\u003ePackage Quantity\u003c\/strong\u003e: 10\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: BOW36790\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51972970250546,"sku":"BOW36790","price":238.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eeb2e95729df849ce5ddbfe2a77ad730_2d722732-a103-46e3-a953-8795f0c812d5.jpg?v=1789971431","url":"https:\/\/voomisupply.com\/products\/bowmalloy-bow36790-hex-lock-nut-1-1-8-7-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
