The nylon insert collar deforms around mating threads during installation, creating prevailing torque that resists loosening from vibration and thermal cycling. At 0.125 inches high with a 1\/4-inch width across flats, this compact fastener is sized for tight assemblies where space is limited. It follows UNC thread standards with a right-hand thread direction, making it compatible with standard inch-series fastener tooling. Installed by millwrights, maintenance technicians, HVAC mechanics, plumbers, and electricians in a wide range of mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for general-purpose mechanical, electrical, and plumbing applications where vibration resistance is required without chemical thread-locking compounds. Typical use cases include equipment panels, bracket assemblies, conduit fittings, and light structural connections in both residential and commercial settings. The zinc plating provides basic corrosion resistance for indoor and protected outdoor environments. It is not intended for high-temperature applications where nylon insert integrity may be compromised.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style provides prevailing torque without adhesives or additional hardware\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general-purpose fastening loads\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion resistance in dry or protected environments\u003c\/li\u003e\n  \u003cli\u003eUNC thread standard for compatibility with standard inch-series bolts and studs\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction follows conventional installation tooling\u003c\/li\u003e\n  \u003cli\u003eCompact 0.125-inch height fits space-constrained assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-use hex lock nut for standard UNC inch-series threaded fastener applications across mechanical, electrical, and plumbing assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by the applicable licensed trade or maintenance technician using a standard hex wrench or socket matching the 1\/4-inch across-flats dimension. De-energize electrical systems and relieve system pressure before replacing fasteners in live assemblies. Nylon insert lock nuts are single-use by design and should not be reused after removal, as the insert loses prevailing torque after the first installation. Follow applicable code requirements, including NEC for electrical enclosures, IPC for plumbing assemblies, or IFGC for gas piping bracket connections, as appropriate to the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 2\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: Zinc-Plated\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\u003eHeight\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.2430 to 0.2510 inches (1\/4 inch nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 0.2680 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: 0.001 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: R52001652\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714166292786,"sku":"R52001652","price":466.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f46f84eb2b7dbb68f44488cad4e4f60.jpg?v=1788497089","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001652-hex-lock-nut-1-4-in-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
