The nylon insert creates interference with the mating thread to resist loosening caused by vibration or torque. Standing 15\/32 inches high with a 1-1\/4 inch width across flats, this nut is dimensionally standard for UNC fastener assemblies. It is installed by mechanics, millwrights, plumbers, and general tradespeople wherever a corrosion-resistant prevailing-torque nut is required. The right-hand thread direction follows standard fastener convention.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for use in corrosive or moisture-prone environments where stainless steel fastener hardware is specified. Typical applications include HVAC equipment mounting, plumbing fixture assemblies, pool and spa equipment frames, electrical enclosure hardware, and general mechanical assemblies requiring vibration resistance. The 18-8 stainless steel grade provides good resistance to rust and oxidation without a sacrificial coating, making it a reliable choice for both indoor and outdoor installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC right-hand thread — standard coarse-thread sizing for broad fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eNylon insert locking style provides prevailing torque to resist loosening under vibration\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction offers corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no plating to chip, peel, or react with stainless hardware\u003c\/li\u003e\n  \u003cli\u003e15\/32 inch height and 1-1\/4 inch width across flats match standard UNC hex nut dimensions\u003c\/li\u003e\n  \u003cli\u003eWidth across points of 1.4030 inches for proper wrench and socket fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC prevailing-torque replacement hex lock nut for 7\/8-9 threaded fastener assemblies requiring an 18-8 stainless steel nylon insert nut.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard 1-1\/4 inch wrench or socket. Power down or de-energize any associated equipment before performing fastener work in electrical or HVAC applications. The nylon insert is single-use by design — a nylon insert lock nut that has been fully run on and removed should be replaced rather than reused, as the insert loses prevailing-torque effectiveness after the first installation. Follow applicable mechanical or structural codes for the specific assembly being fastened.\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\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: 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\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 15\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-1\/4 inches (1.2390 to 1.2520 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 1.4030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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-THN-87C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691533140274,"sku":"1-THN-87C","price":45.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da605438119a3834d46436c9efde34d5.jpg?v=1788286631","url":"https:\/\/voomisupply.com\/products\/value-collection-1-thn-87c-hex-lock-nut-7-8-9-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
