The nylon insert creates friction against mating threads to resist loosening caused by vibration and torque cycling. At 49\/64 inches in height with a 15\/16-inch width across flats, this nut installs with a standard wrench and is suited for general-purpose fastening applications in mechanical, HVAC, plumbing, and structural assemblies. Right-hand thread direction follows standard UNC convention. The zinc-plated finish provides a basic level of corrosion resistance for indoor and light-duty applications.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is used in a wide range of trade and light industrial fastening scenarios where vibration resistance is required. Typical applications include equipment mounting, duct and frame assembly, pump and motor mounting, and general mechanical service work. It is appropriate for use wherever a 5\/8-11 UNC threaded fastener is specified and a locking nut is preferred over a split lock washer or thread-locking compound. Sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style resists loosening under vibration without damaging mating threads\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction for general-purpose strength requirements\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish for basic corrosion protection in dry or low-moisture environments\u003c\/li\u003e\n\u003cli\u003eRight-hand thread, 5\/8-11 UNC for compatibility with standard inch-series threaded fasteners\u003c\/li\u003e\n\u003cli\u003eHeight of 49\/64 inches and 15\/16-inch width across flats for use with standard hex wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with any standard 5\/8-11 UNC inch-series threaded bolt or stud requiring a locking hex nut in general-purpose Grade 2 steel fastening applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a standard hex wrench or socket sized to 15\/16 inches across flats. Follow applicable torque guidelines for Grade 2 fasteners per the specific assembly specification. Nylon insert lock nuts are single-use by design and should not be reused after removal, as the nylon insert loses clamping effectiveness after the first seating cycle. Ensure mating bolt threads are clean and undamaged before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eThread Size\u003c\/strong\u003e: 5\/8-11\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\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: 49\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 15\/16 inches\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: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MP34277\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697504583986,"sku":"MP34277","price":18.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8177b9f76906acd0dde2c9bf4aab0957.jpg?v=1788352236","url":"https:\/\/voomisupply.com\/products\/value-collection-mp34277-hex-lock-nut-5-8-11-grade-2-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
