It features a right-hand thread in a 7\/8-14 UNF thread size and uses an internal nylon insert to resist loosening caused by vibration and torque. The nylon collar grips the mating fastener threads without damaging them, providing reliable prevailing-torque locking in demanding environments. At 63\/64 inches tall with 1-1\/4 inches across the flats, this nut fits standard hex tooling. It is installed by maintenance technicians, pipefitters, and mechanical contractors where corrosion resistance and vibration resistance are priorities.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for applications in corrosive environments where carbon steel fasteners would degrade. Common uses include marine equipment, food processing machinery, chemical handling systems, HVAC framework assemblies, and plumbing fixture installations. The 18-8 stainless steel construction offers good resistance to rust, oxidation, and mild chemical exposure. The UNF thread form is standard in precision mechanical and fluid-handling assemblies where fine thread engagement is required for higher clamp loads in thinner materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening from vibration without damaging mating threads\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 stainless steel construction provides corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003e7\/8-14 UNF right-hand thread for use with standard fine-thread fastener assemblies\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch width across flats accepts standard hex wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eHeight of 63\/64 inches provides full thread engagement depth\u003c\/li\u003e\n  \u003cli\u003eSingle-piece quantity for targeted replacement or low-volume maintenance use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-installation nylon insert hex lock nut for 7\/8-14 UNF fine-thread fastener assemblies requiring 18-8 stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand-threading the nut onto a compatible 7\/8-14 UNF male fastener, then torquing to the assembly specification using a standard hex wrench or socket. The nylon insert is a single-use locking element and should not be reused once fully seated and removed, as repeated cycling degrades the prevailing-torque resistance. Always confirm thread direction and thread class compatibility before installation. No special tools beyond standard hand or power wrenches are required.\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\u003eLocking Style\u003c\/strong\u003e: Nylon Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF\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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\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: 63\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\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\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: 1-N-87F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698800623922,"sku":"1-N-87F","price":26.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a21ccdff3a81ed8a7e926652613d066_2ef25eda-462e-42ba-95b7-92bfbb662c4f.jpg?v=1788368131","url":"https:\/\/voomisupply.com\/products\/value-collection-1-n-87f-hex-lock-nut-7-8-14-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
