Built from Grade 2 steel with a zinc-plated finish, this fastener delivers reliable corrosion resistance for general-purpose applications. The nylon collar compresses against the thread flanks to create a prevailing torque that holds the nut in position without the need for secondary locking devices. Measuring 3\/16 inches in height with a 3\/8-inch width across flats, it follows a standard UNC right-hand thread pattern. Electricians, plumbers, HVAC technicians, and mechanical contractors use this type of nut in equipment assemblies, panel mounting, and structural connections throughout trade and light industrial work.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for residential and light commercial applications where vibration-resistant fastening is required. Common install scenarios include securing equipment brackets, junction box hardware, pipe hanger assemblies, and mechanical panel components. The zinc-plated finish provides adequate corrosion protection for indoor and sheltered outdoor environments. The UNC thread standard makes it compatible with standard inch-series fastener systems widely used across North American trade applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening under vibration without secondary hardware\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides solid strength for general-purpose fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers corrosion resistance in standard service environments\u003c\/li\u003e\n  \u003cli\u003eUNC right-hand thread pattern matches standard inch-series bolts and studs\u003c\/li\u003e\n  \u003cli\u003eCompact 3\/16-inch height suits applications with limited axial space\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch width across flats fits standard hex wrench and socket tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stocking fastener for use with standard UNC inch-series threaded bolts and studs in residential, commercial, and light industrial equipment assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNylon insert lock nuts are installed by hand-threading onto the mating fastener before driving with a standard hex wrench or socket. Ensure the mating bolt or stud thread class is compatible with UNC specifications before installation. Nylon insert nuts are generally considered single-use; once the nylon collar has been compressed and removed, the prevailing torque retention is reduced and replacement is recommended. Always de-energize and isolate any electrical or mechanical system before servicing fastened connections.\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: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/8 inches (0.3670 to 0.3760 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 0.4100 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: 0.0035 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: R52001651\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722979574066,"sku":"R52001651","price":403.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41409a18056dc400c593259ec5e8e4f2.jpg?v=1788598773","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001651-hex-lock-nut-3-8-in-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
