The nylon insert creates interference with the mating thread, resisting loosening caused by vibration and dynamic loads. At 5\/16 inches high with a 7\/16-inch width across flats, this fastener follows Unified National Coarse (UNC) thread standards with a right-hand thread direction. It is suited for structural and mechanical assemblies where a reliable, reusable locking fastener is required under load.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is used in a wide range of industrial, mechanical, and trade applications where vibration resistance is critical. Typical installations include HVAC equipment frames, pump and motor mounting hardware, electrical panel supports, and general structural assemblies. The zinc yellow dichromate finish provides a measure of corrosion resistance for use in mildly demanding environments. This fastener is sold individually with a minimum order quantity of 50 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening under vibration and torque\u003c\/li\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile strength\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC right-hand thread for broad compatibility with standard fastener systems\u003c\/li\u003e\n  \u003cli\u003eCompact profile: 5\/16 inches high, 7\/16 inches across flats\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC 1\/4-20 hex lock nut suitable for use with any matching 1\/4-20 threaded fastener in Grade 8 steel applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove using a standard 7\/16-inch wrench or socket. Nylon insert lock nuts are intended for use on clean, undamaged threads to ensure the insert seats properly. The nylon insert may degrade at sustained elevated temperatures, so verify suitability for the thermal environment before installation. Always de-energize or lock out equipment before performing fastener work on energized assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread 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\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: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Nylon\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: 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: MP39651\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720852013362,"sku":"MP39651","price":16.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1813d2b5f73aa09461752456091b73d4.jpg?v=1788569973","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39651-hex-lock-nut-1-4-20-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
