Built from 18-8 stainless steel with a bright, uncoated finish, it offers solid corrosion resistance for general-purpose and marine-adjacent applications. The 5\/8-11 UNC thread size and right-hand thread direction make it a standard fit for a wide range of structural and mechanical assemblies. At 55\/64 inches high with a 1-1\/16 inch width across flats, this heavy hex profile provides greater bearing surface than standard hex, distributing load more evenly across the joint. Installed by millwrights, pipefitters, and maintenance technicians wherever a reliable prevailing-torque locking solution is needed.\u003c\/p\u003e\n\u003cp\u003eThis lock nut is suited for industrial, commercial, and mechanical installations where vibration resistance is a priority. The nylon insert creates a prevailing torque that resists self-loosening without requiring a secondary locking element such as a lock washer or thread adhesive. Its 18-8 stainless steel construction handles exposure to moisture and mild corrosives, making it appropriate for HVAC structural connections, plumbing equipment mounts, and general plant maintenance assemblies requiring a 5\/8-11 UNC fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style provides reliable prevailing torque without additional hardware\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel material offers corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n  \u003cli\u003eHeavy hex profile with 1-1\/16 inch width across flats increases bearing surface over standard hex\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC right-hand thread for compatibility with standard inch-series fasteners\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable where bare stainless is acceptable or required\u003c\/li\u003e\n  \u003cli\u003eWidth across points of 1.1750 inches accommodates standard heavy hex tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard procurement item for assemblies 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\u003eInstall with a standard heavy hex wrench or socket sized for the 1-1\/16 inch width across flats. Power down or de-energize any associated equipment before performing fastener work on mechanical systems. Nylon insert lock nuts are intended for single-use applications — the nylon element loses clamping integrity after removal and the nut should not be reused in critical joints. Follow applicable mechanical and structural codes for torque sequence when used in multi-bolt flange or structural connections.\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\u003eFastener Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: 55\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-1\/16 inches (1.0450 to 1.0670 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 1.1750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161716\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-NU-62C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714150760754,"sku":"31-NU-62C","price":45.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/899c607fa6073e29ec912f41d804c5be.jpg?v=1788496924","url":"https:\/\/voomisupply.com\/products\/value-collection-31-nu-62c-heavy-hex-lock-nut-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
