The nylon insert creates interference with the mating thread to resist vibration-induced loosening without damaging the fastener. At 0.75 inches tall with a 15\/16-inch width across flats, this nut installs with standard hex tooling. The right-hand thread direction follows standard UNF convention. Weighing 0.083 pounds per unit, it suits applications where corrosion resistance and reliable thread retention are both required. Licensed tradespeople and maintenance technicians working with stainless fastener assemblies will find this a direct-fit prevailing-torque solution.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is suited for light industrial, HVAC structural, plumbing support, and electrical enclosure assembly applications where stainless steel corrosion resistance is required and vibration loosening is a concern. The nylon insert style is appropriate for operating temperatures that do not exceed the thermal limits of the nylon collar. It is used in both residential and commercial mechanical installations on 5\/8-18 UNF threaded fastener assemblies requiring a removable but vibration-resistant connection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style resists vibration loosening without thread damage\u003c\/li\u003e\n\u003cli\u003eGrade 18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n\u003cli\u003e5\/8-18 UNF right-hand thread for standard fastener compatibility\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no added coating to interfere with tight-tolerance fits\u003c\/li\u003e\n\u003cli\u003eWidth across flats of 15\/16 inches fits standard SAE hex tooling\u003c\/li\u003e\n\u003cli\u003eInch measurement system; meets UNF fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or general-use hex lock nut for any 5\/8-18 UNF threaded stud or bolt application requiring a nylon insert prevailing-torque nut in 18-8 stainless steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical, HVAC, plumbing, or electrical tradespeople following applicable codes and fastener torque guidelines for the specific assembly. Always ensure the mating fastener thread specification matches 5\/8-18 UNF before installation. Nylon insert lock nuts are single-use by design — the nylon collar loses prevailing torque effectiveness after removal and should not be reused in critical applications. Do not use in high-temperature environments that exceed the rated service temperature of nylon insert materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 5\/8-18\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\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 15\/16 inches (0.928 to 0.940 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 1.051 inches\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: 0.083 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-62F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704048386354,"sku":"1-N-62F","price":35.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48e88b35921b659fd7a9698a23120e0d.jpg?v=1788420268","url":"https:\/\/voomisupply.com\/products\/value-collection-1-n-62f-hex-lock-nut-5-8-18-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
