Sized for 3\/8-16 UNC threads, it is manufactured from Grade 2 steel with an uncoated finish. The nylon insert deforms around the mating threads when installed, creating a prevailing torque that prevents back-out without the need for thread-locking compounds. At 35\/64 inches in height and 11\/16 inches across the flats, this nut follows standard heavy hex dimensions. It is a right-hand-thread fastener used across general mechanical assembly, structural connections, and maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for general industrial, mechanical, and trade assembly work where vibration resistance is required and reusability is acceptable. Common applications include HVAC equipment mounting, electrical panel and enclosure assembly, plumbing fixture brackets, and general structural fastening. The nylon insert locking style is appropriate for metal-to-metal clamping scenarios where temperature exposure stays within the nylon insert operating range. Minimum order quantity is 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert provides prevailing torque locking without additional thread-locking compounds\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread size with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for general-purpose load applications\u003c\/li\u003e\n  \u003cli\u003eHeavy hex profile — 11\/16 inches across flats for increased wrench bearing surface\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; suitable for dry or protected interior environments\u003c\/li\u003e\n  \u003cli\u003eConforms to inch system of measurement and UNC fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock fastener for any assembly using 3\/8-16 UNC right-hand-thread fasteners where a prevailing torque nylon insert hex lock nut is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard combination or open-end wrench sized for 11\/16 inches across flats. Power down or de-energize any equipment before fastener service on live assemblies. Nylon insert lock nuts are generally rated for a limited number of removal and reinstallation cycles — replace the nut if the prevailing torque feel is lost on reuse. Do not use in applications where sustained temperatures will degrade the nylon insert.\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: 3\/8-16\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 35\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: R-34820-3\/8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692672057650,"sku":"R-34820-3\/8","price":37.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_e2cc5c0e-4e92-42ca-82f4-c7f7e5b375c1.jpg?v=1788300946","url":"https:\/\/voomisupply.com\/products\/value-collection-r-34820-3-8-hex-lock-nut-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
