The nylon insert creates interference with mating threads to resist loosening caused by vibration, torque, and thermal cycling. At 5\/16 inches high with a 7\/16-inch width across flats, this nut is sized for standard 1\/4-28 fine-thread fastener assemblies. The right-hand thread direction follows standard convention. Installers in HVAC, plumbing, electrical, and mechanical service work reach for 18-8 stainless when corrosion resistance matters alongside reliable locking performance.\u003c\/p\u003e\u003cp\u003eThis lock nut is suited for light-to-medium fastening applications where vibration resistance is required and a permanent locking solution is not. Common uses include equipment panel assemblies, mounting brackets, conduit support hardware, and mechanical components exposed to moisture or mild corrosives. The 1\/4-28 fine thread pitch provides higher thread engagement per inch than coarse-thread equivalents, making it a preferred choice where precise clamping force control is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style resists loosening under vibration without damaging mating threads\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction provides corrosion resistance for wet or outdoor environments\u003c\/li\u003e\n\u003cli\u003e1\/4-28 UNF fine thread for higher thread engagement and controlled clamping\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, standard convention for most fastener assemblies\u003c\/li\u003e\n\u003cli\u003e5\/16-inch height and 7\/16-inch width across flats fit standard hex tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1\/4-28 UNF right-hand threaded fasteners in inch-measurement assemblies requiring a reusable nylon insert lock nut.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a standard hex wrench or socket sized for 7\/16-inch flats. Nylon insert lock nuts are reusable but locking torque decreases with each removal and reinstallation cycle — replace when locking resistance is noticeably reduced. Always de-energize electrical equipment and isolate mechanical systems before disassembling fastened components. Follow applicable mechanical and electrical codes for fastener torque requirements specific to the assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\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\u003eMaterial\u003c\/strong\u003e: 18-8 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF\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: 0.009 pounds\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: 1-N-25F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689944809778,"sku":"1-N-25F","price":1785.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9ababd202d03d99b6a1104eced01855.jpg?v=1788265532","url":"https:\/\/voomisupply.com\/products\/value-collection-1-n-25f-hex-lock-nut-1-4-28-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
