The nylon insert deforms around mating threads when torqued, creating prevailing torque that resists loosening from vibration and dynamic loading. At 7\/16 inches high with a 9\/16-inch width across flats, this nut fits standard 9\/16-inch hex tooling. Right-hand thread direction follows conventional fastener orientation. The zinc plating provides moderate corrosion resistance in typical indoor and sheltered applications. This nut is sold individually with a minimum order quantity of 25 pieces.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for general mechanical assembly, HVAC equipment mounting, light structural connections, plumbing fixture attachment, and electrical panel or enclosure work where a standard 3\/8-16 threaded fastener must resist vibration-induced loosening. It is appropriate for residential and light commercial applications where Grade 2 steel meets load requirements. Installers working on equipment frames, fan assemblies, pump mounts, and conduit support hardware will find this nut suitable for routine service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style provides prevailing torque resistance against vibration loosening without secondary locking hardware\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread size is one of the most common inch-series fastener sizes in trade applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general-purpose, non-critical fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers moderate corrosion protection in dry to lightly humid environments\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard 3\/8-16 bolts, studs, and threaded rod\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch width across flats works with standard open-end, box-end, and socket wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any standard 3\/8-16 UNC inch-series bolt, cap screw, or threaded rod in general mechanical and trade assembly applications.\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 single-use by design — the nylon deforms on first installation and reuse on the same threads reduces locking effectiveness. Always inspect the nylon insert before reuse and replace if damaged or flattened. Follow applicable mechanical and structural codes for fastener grade requirements on load-bearing 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 with Nylon Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\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\u003eInsert Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.4375 inches (7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.5625 inches (9\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNC\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: 0.01 pounds\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: 25\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: 34351\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695190081842,"sku":"34351","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9fe2050bbe6daa18ec248e1d980a91.jpg?v=1788332300","url":"https:\/\/voomisupply.com\/products\/value-collection-34351-hex-lock-nut-3-8-16-nylon-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
