Threaded to a 7\/8-9 UNC specification with a right-hand thread direction, this nut is manufactured from Grade 2 steel with a bright uncoated finish. It measures 31\/32 inches in height and 1-7\/16 inches across the flats. The nylon insert creates interference with the bolt thread, providing a mechanical locking action without requiring adhesives or external lock washers. It is installed by maintenance technicians, millwrights, and general contractors across a wide range of structural and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis heavy hex lock nut is suited for general industrial, commercial, and construction fastening applications where vibration resistance is required. The 7\/8-9 UNC thread size fits standard fractional bolts and threaded rod commonly found in structural steel connections, machinery frames, equipment mounting, and utility installations. The nylon insert is effective for applications that do not involve sustained exposure to high heat, as extreme temperatures can degrade insert performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert provides mechanical locking action to resist loosening from vibration\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC right-hand thread for compatibility with standard fractional fasteners\u003c\/li\u003e\n  \u003cli\u003eHeavy hex profile offers greater wrench engagement and torque capacity than standard hex\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for general-purpose strength requirements\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for indoor or protected environments\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging with no minimum order requirement beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fastening component for any assembly using 7\/8-9 UNC threaded bolts or rod in inch-measurement applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand-threading the nut onto the mating bolt or stud until the nylon insert engages, then driving to the required torque using a standard open-end, box-end, or socket wrench sized for a 1-7\/16 inch hex. Nylon insert lock nuts are generally considered single-use fasteners — once removed, the locking effectiveness of the insert is reduced and replacement is recommended. Do not use this nut in applications where continuous temperatures exceed the rated limits of nylon inserts. Follow applicable mechanical and structural codes for the specific assembly type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Heavy Hex Lock Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Style\u003c\/strong\u003e: Nylon Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Nylon\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 2\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: 1-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\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: 0.1 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NLI2087NU-025BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701861286194,"sku":"NLI2087NU-025BX","price":19.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7b1625e7e6688e16297e3ae573a0897_b686474c-4198-4858-b281-49ed061c117a.jpg?v=1788406167","url":"https:\/\/voomisupply.com\/products\/value-collection-nli2087nu-025bx-hex-lock-nut-7-8-9","provider":"Voomi Supply","version":"1.0","type":"link"}
