Built from 18-8 stainless steel with a bright uncoated finish, this nut offers solid corrosion resistance for both indoor and outdoor applications. It features a 5\/8-11 UNC thread size with right-hand thread direction and measures 39\/64 inches in height with a 1-1\/16 inch width across flats. The nylon insert locks the nut in place by gripping the bolt threads, preventing loosening under dynamic loads. Installers in mechanical, plumbing, electrical, and HVAC trades use this style of fastener when securing structural or equipment connections that are subject to movement or vibration.\u003c\/p\u003e\n\u003cp\u003eThis heavy hex lock nut is suited for general industrial and trade applications requiring a corrosion-resistant stainless steel fastener. Common uses include mechanical equipment mounting, pipe support systems, electrical enclosure assembly, and HVAC equipment installation. The 5\/8-11 UNC thread is a standard coarse-thread specification, making this nut compatible with a wide range of threaded rod, bolts, and studs in that size. It is sold individually, making it appropriate for single-unit replacement or low-quantity repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening caused by vibration and dynamic loads\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC coarse-thread specification for broad compatibility with standard fasteners\u003c\/li\u003e\n  \u003cli\u003eHeavy hex profile provides additional wrench-bearing surface for higher torque applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains dimensional accuracy without coating buildup on threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction conforms to standard fastener convention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-use fastener for applications requiring a 5\/8-11 UNC heavy hex nylon insert lock nut in 18-8 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fastener is installed by hand-threading onto a compatible 5\/8-11 UNC bolt or threaded rod, then torqued to spec using an appropriate wrench. Always de-energize or shut down the equipment being fastened before beginning installation in electrical or HVAC systems. The nylon insert is single-use by design and should not be reused once fully seated, as repeated cycling degrades the locking effectiveness. Follow applicable mechanical codes and equipment manufacturer guidelines when determining final torque values.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Heavy Hex Lock Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\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: 18-8 Stainless Steel\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: 39\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-1\/16 inches (1.0520 to 1.0640 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 1.1910 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.092 pounds\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: 31-NTU-62C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722332242226,"sku":"31-NTU-62C","price":34.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b4da378004c7833de8a3279705babb9.jpg?v=1788589520","url":"https:\/\/voomisupply.com\/products\/value-collection-31-ntu-62c-heavy-hex-lock-nut-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
