The nylon insert creates interference with mating threads to resist loosening caused by vibration and torque. This fastener measures 29\/64 inches high with a 9\/16-inch width across flats, making it a standard-profile nut suited for general mechanical and structural assembly work. Electricians, plumbers, HVAC technicians, and general contractors use this nut wherever a reliable, vibration-resistant threaded connection is required on 3\/8-16 fastener assemblies.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is appropriate for residential and light commercial applications involving steel framing, equipment mounting, conduit support hangers, pipe strut assemblies, and mechanical panel work. The zinc plating provides corrosion resistance suitable for indoor and protected outdoor environments. Right-hand thread direction conforms to standard UNC fastener practice. This nut is sold individually but is subject to a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening under vibration without damaging mating thread surfaces\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC right-hand thread — compatible with standard inch-series fasteners\u003c\/li\u003e\n  \u003cli\u003eGrade B steel construction provides reliable strength for general mechanical assembly\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers corrosion resistance for indoor and protected environments\u003c\/li\u003e\n  \u003cli\u003e29\/64-inch height and 9\/16-inch width across flats conform to standard hex nut dimensions\u003c\/li\u003e\n  \u003cli\u003eWidth across points of 0.622 inches ensures fit with standard 9\/16-inch wrenches and sockets\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 threaded bolt or stud in inch-series mechanical assemblies across HVAC, plumbing, electrical, and general construction applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard 9\/16-inch wrench or socket. Power down or de-energize any electrical equipment before securing fasteners on panel or conduit assemblies. Nylon insert lock nuts are single-use by design — once the nylon insert has been fully threaded past a bolt, the locking torque is reduced and the nut should not be reused in critical applications. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.\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\u003eFastener Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\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: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\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: 0.018 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161716\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: R52001687\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689717334322,"sku":"R52001687","price":15151.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fd4801c8c82596b25c652657e1623ec.jpg?v=1788263384","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001687-hex-lock-nut-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
