Manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance, this fastener is a standard choice for mechanical assemblies, HVAC equipment mounting, plumbing fixture hardware, and general trade applications. The nylon insert creates interference with the mating thread, maintaining clamp load without the need for additional locking hardware. At 15\/32 inches high with an 11\/16-inch width across flats, it fits standard 7\/16-inch drive and open-end tooling.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is suited for residential and light commercial applications where a reusable, prevailing-torque fastener is required. Typical install scenarios include securing brackets, fan assemblies, pump mounts, and structural components in HVAC, plumbing, and electrical panel work. The right-hand thread direction is standard for the vast majority of mechanical fastening applications. Sold individually with a minimum order quantity of 25 units, this nut is appropriate for both single-unit service repairs and small-batch production or maintenance stocking.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style resists loosening from vibration without additional locking hardware\u003c\/li\u003e\n\u003cli\u003e7\/16-20 UNF right-hand thread for compatibility with standard inch-series fastener systems\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction suitable for general-duty mechanical and trade applications\u003c\/li\u003e\n\u003cli\u003eZinc finish provides basic corrosion protection in dry or mildly humid environments\u003c\/li\u003e\n\u003cli\u003e15\/32-inch height and 11\/16-inch width across flats fit standard open-end and socket tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNF inch-series hex lock nut for general mechanical, HVAC, plumbing, and electrical assembly applications requiring a 7\/16-20 prevailing-torque fastener.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires standard open-end or socket wrenches sized for an 11\/16-inch hex. Always ensure the mating bolt or stud is clean and free of damage before threading the nut on by hand first to avoid cross-threading. De-energize or shut down any equipment before servicing fasteners on live mechanical or electrical assemblies. The nylon insert may show reduced locking performance if reused multiple times; replace if locking torque feels significantly reduced.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF\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 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 15\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 11\/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: 25\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: MP34285\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702003138866,"sku":"MP34285","price":20.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/422f8f4e5ac3093de123c9d122eb2b06.jpg?v=1788407978","url":"https:\/\/voomisupply.com\/products\/value-collection-mp34285-hex-lock-nut-7-16-20-grade-2-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
