Threaded at 7\/8-14 with a right-hand thread direction, it features a Bowma-Guard cadmium waxed finish that provides corrosion resistance in demanding service environments. The nut measures 1.2969 inches across flats and 0.847 inches in height. It is suited for heavy-duty mechanical assemblies where standard Grade 5 or Grade 8 fasteners do not meet load requirements. Licensed mechanics, millwrights, and maintenance technicians working on industrial equipment, agricultural machinery, or heavy vehicles are the typical installers.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is used in applications requiring a prevailing-torque locking mechanism in inch-series assemblies. The 7\/8-14 fine thread pitch provides greater thread engagement and improved resistance to loosening compared to coarse-thread equivalents. The Bowma-Guard finish makes it appropriate for environments with exposure to moisture, light chemicals, or outdoor conditions. It ships in packages of 25 units, making it practical for shop stock or service fleet inventory.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 9 steel construction for high-strength, high-torque applications\u003c\/li\u003e\n\u003cli\u003e7\/8-14 fine thread for greater thread engagement and vibration resistance\u003c\/li\u003e\n\u003cli\u003eBowma-Guard cadmium waxed finish for corrosion protection in harsh environments\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction per inch measurement system standards\u003c\/li\u003e\n\u003cli\u003eWidth across flats of 1.2969 inches (1-19\/64 inches) for standard wrench compatibility\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 25 for shop stock efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fastener for inch-series mechanical assemblies requiring a 7\/8-14 hex lock nut in Grade 9 steel with a prevailing-torque locking feature.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright familiar with high-strength fastener torque requirements. Always consult the equipment manufacturer's torque specification chart for Grade 9 fasteners before installation. Ensure mating threads are clean, undamaged, and free of debris before engaging the nut. Do not reuse prevailing-torque lock nuts that have been previously removed, as the locking element may be compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 7\/8-14\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\u003eWidth Across Flats\u003c\/strong\u003e: 1.2969 inches (1-19\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.847 inches\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: 25\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: BOW36803\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51974150258994,"sku":"BOW36803","price":47.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eeb2e95729df849ce5ddbfe2a77ad730_2e264053-1427-4443-903f-eda85309b634.jpg?v=1789976061","url":"https:\/\/voomisupply.com\/products\/bowmalloy-bow36803-hex-lock-nut-7-8-14-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
