The nylon insert deforms around mating threads under torque, creating resistance to loosening caused by vibration and dynamic loading. The nut measures 1-7\/64 inches in height and 2 inches across the flats. It conforms to ASME B 18.16.6, the standard governing prevailing-torque hex nuts with nonmetallic inserts. Installation and removal require a standard 2-inch wrench. This fastener is used by mechanical contractors, millwrights, plumbers, and general industrial assemblers wherever vibration-resistant fastening is required.\u003c\/p\u003e\u003cp\u003eThe NLI2125NTU-005B is suited for general-purpose structural and mechanical assemblies where UNC thread engagement and vibration resistance are required. Typical applications include equipment mounting, pipe hanger hardware, structural steel connections, and industrial machinery assembly. The right-hand thread direction is compatible with standard UNC threaded rod and bolts in the 1-1\/4-7 pitch. This nut is intended for service environments where a metallic locking feature is not specified and a nylon insert is acceptable per the design requirement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style provides vibration-resistant prevailing torque per ASME B 18.16.6\u003c\/li\u003e\n\u003cli\u003e1-1\/4-7 UNC thread size with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction for general-purpose fastening applications\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no added plating or coating\u003c\/li\u003e\n\u003cli\u003eHeight of 1-7\/64 inches and 2 inches width across flats\u003c\/li\u003e\n\u003cli\u003eDoes not meet military specifications — commercial-grade fastener\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1-1\/4-7 UNC threaded fasteners including bolts, studs, and threaded rod conforming to inch-series UNC thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed using a properly sized open-end, box-end, or socket wrench sized for 2 inches across the flats. Nylon insert lock nuts are single-use fasteners — the nylon insert loses prevailing torque effectiveness after removal and should not be reused in critical applications. De-energize, depressurize, or otherwise isolate the assembly before servicing any connected fasteners. Consult the applicable mechanical or structural specification for torque requirements, as none are specified for this product.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eHeight\u003c\/strong\u003e: 1-7\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 2 inches\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\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B 18.16.6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\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: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: NLI2125NTU-005B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689741484338,"sku":"NLI2125NTU-005B","price":123.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_0891db5d-1d32-4c7b-9d48-769eddf9fc34.jpg?v=1788263694","url":"https:\/\/voomisupply.com\/products\/value-collection-nli2125ntu-005b-hex-lock-nut-1-1-4-7","provider":"Voomi Supply","version":"1.0","type":"link"}
