Constructed from 18-8 stainless steel, this prevailing-torque nut resists corrosion and maintains clamping force in applications where standard hex nuts would back off over time. The nylon insert deforms against mating threads to create friction-based retention without damaging thread surfaces. The nut measures 15\/16 inches across the flats and stands 25\/64 inches high, with an uncoated finish suited for environments where coating adhesion or chemical compatibility is a concern. Mechanical contractors, plumbers, and equipment installers use this type of fastener across a wide range of structural and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is appropriate for residential and light commercial mechanical assemblies requiring secure, vibration-resistant fastening on 5\/8-18 UNF threaded rod, bolts, or studs. Typical applications include HVAC equipment mounting, pump and motor bracket assemblies, piping support hardware, and general-duty mechanical fastening where a standard nut would require secondary locking provisions such as thread-locking compound or a secondary jam nut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF thread for fine-pitch engagement on standard threaded fasteners\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n  \u003cli\u003eNylon insert delivers prevailing-torque retention without thread damage\u003c\/li\u003e\n  \u003cli\u003e15\/16 inches width across flats fits standard SAE hex wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eUncoated finish eliminates coating compatibility concerns\u003c\/li\u003e\n  \u003cli\u003eSold individually for single-point replacement or low-volume service needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard prevailing-torque replacement for 5\/8-18 UNF hex lock nut applications in mechanical, HVAC, plumbing, and equipment support assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation does not require specialized tools beyond a standard 15\/16-inch hex wrench or socket. Power down or de-energize any associated equipment before accessing fastener locations in electrical or mechanical enclosures. The nylon insert is rated for single use in most structural applications — replace the nut rather than reusing it after removal. Follow applicable torque guidelines from the equipment manufacturer or relevant mechanical codes when specified.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Lock Nut with 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\u003eWidth Across Flats\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 25\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.039 pounds\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-THN-62F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51719349895474,"sku":"1-THN-62F","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a95e82a685ca3eef2839fb628262fd4e_59265a27-671d-4437-b311-6c97d85cfa06.jpg?v=1788558960","url":"https:\/\/voomisupply.com\/products\/value-collection-1-thn-62f-hex-lock-nut-5-8-18-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
