The nylon insert creates interference with mating thread flanks to resist vibration-induced loosening without damaging fastener threads. At 17\/64 inches high and 1\/2 inch across the flats, this nut fits standard hex tooling and is suited for applications where a full-height hex nut would be excessive. Right-hand thread direction follows standard UNF convention. Installers across HVAC, plumbing, electrical, and general mechanical trades use this style of prevailing-torque nut wherever vibration resistance is required.\u003c\/p\u003e\n\u003cp\u003eThis nylon insert lock nut is appropriate for light-to-medium fastening applications on 5\/16-24 UNF threaded fasteners in residential and commercial installations. Common install scenarios include equipment panel assembly, bracket mounting, and component attachment on HVAC units, electrical enclosures, and plumbing fixtures. The zinc plating provides baseline corrosion resistance for indoor and mildly humid environments. These nuts are sold individually but require a minimum order quantity of 100 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening under vibration without thread damage\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for standard light-to-medium load applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides baseline corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e5\/16-24 UNF right-hand thread for compatibility with standard inch-series fasteners\u003c\/li\u003e\n  \u003cli\u003eLow-profile at 17\/64 inches high, conserving axial space in tight assemblies\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch width across flats fits common standard hex sockets and wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/16-24 UNF externally threaded fasteners conforming to inch-series unified fine thread standards.

Use a standard hex socket or open-end wrench sized to 1\/2 inch across the flats. Ensure mating threads are clean and free of debris before installation. Follow applicable equipment manufacturer torque guidelines, as no product-specific torque values are provided with this fastener.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF (Unified National Fine)\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\u003eLocking Style\u003c\/strong\u003e: Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Nylon\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 17\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0075 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does not meet military specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: R50000028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695211675954,"sku":"R50000028","price":928.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d12b07ed1863916ce853b578b36c3eb.jpg?v=1788332618","url":"https:\/\/voomisupply.com\/products\/value-collection-r50000028-hex-lock-nut-5-16-24-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
