Sized at 3\/8-16 UNC thread, this nut is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in indoor and light-duty outdoor environments. The nylon insert creates interference with the bolt thread, resisting loosening from vibration and torque cycling without the need for adhesive thread-locking compounds. At 35\/64 inches high and 39\/64 inches across the flats, it fits standard hex tooling.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for residential and light commercial applications where a secure, reusable fastener is required. Typical uses include equipment mounting, ductwork hardware, electrical enclosures, pump and motor assemblies, and structural bracketing. The right-hand thread direction is standard for general fastener work. Minimum order quantity is 50 pieces, making this appropriate for shop stock, service vehicle inventory, or project-quantity procurement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists vibration-induced loosening without adhesives\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC right-hand thread for compatibility with standard inch-series bolts and studs\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets general-purpose fastener requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for indoor and light-duty applications\u003c\/li\u003e\n  \u003cli\u003eHeavy hex profile at 39\/64 inches across flats allows firm wrench engagement\u003c\/li\u003e\n  \u003cli\u003eWidth across points of 0.763 inches suits standard open-end and socket tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/8-16 UNC inch-series bolts and threaded rod in general mechanical and trade fastener applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove using a standard 39\/64-inch or equivalent open-end, box-end, or socket wrench. Nylon insert lock nuts can be reused a limited number of times before the insert loses effective locking force; replace if the nut spins freely without resistance. Always de-energize and lock out electrical equipment before fastening hardware inside enclosures. Follow applicable mechanical codes for torque requirements based on joint application.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eHeight\u003c\/strong\u003e: 35\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 39\/64 inches (0.675 to 0.691 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 0.763 inches\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: Zinc-Plated\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: 0.036 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\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: R52001619\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720804041010,"sku":"R52001619","price":4166.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39a5b00c1ccd94a5883589d81b89d2ad.jpg?v=1788569341","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001619-hex-lock-nut-3-8-16-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
