The nylon insert compresses around the mating thread when torqued, creating prevailing-torque resistance without a secondary fastener or adhesive. This style of lock nut is used across plumbing, HVAC, and mechanical assembly applications where vibration resistance is needed and the assembly may require periodic disassembly. The 3\/8-16 UNC thread designation follows Unified National Coarse standards. At 0.0195 pounds per unit, the nut ships in a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003cp\u003eThis nut is suited for residential and light commercial mechanical systems, fluid handling assemblies, HVAC equipment mounting, and general fastening applications where brass construction is specified for corrosion resistance or to avoid galling on brass or copper mating hardware. Right-hand thread direction is standard. The nylon insert is rated for typical operating temperature ranges found in HVAC and plumbing service environments. Licensed mechanics, plumbers, and HVAC technicians commonly stock this size for field repairs and equipment installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert provides prevailing-torque locking without thread adhesive\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion and is compatible with copper and brass mating hardware\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread — widely used standard size across trade applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no plating that can chip or flake in wet environments\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction for standard installation\u003c\/li\u003e\n  \u003cli\u003eSold in multiples of 10 — practical for field stock and service kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC hex lock nut for use with any 3\/8-16 threaded fastener or stud where a nylon insert prevailing-torque nut is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard 9\/16-inch wrench or socket. Nylon insert lock nuts are designed for single-use or limited-reuse applications — the insert loses clamping effectiveness after repeated removal and reinstallation. Do not exceed the temperature rating of the nylon insert, and avoid using these nuts in applications with sustained elevated heat that could degrade the insert material. Shut down and de-energize any equipment before accessing fasteners on live mechanical or electrical assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eMaterial\u003c\/strong\u003e: Brass\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 29\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 9\/16 inches (0.553 to 0.564 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 0.622 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0195 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 7-N-37C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714187034930,"sku":"7-N-37C","price":2315.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/894efa527d770504df4bcbc6bbb5756c.jpg?v=1788497400","url":"https:\/\/voomisupply.com\/products\/value-collection-7-n-37c-hex-lock-nut-3-8-16-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
