The nylon insert deforms around the mating thread when the nut is torqued down, creating prevailing torque that resists vibration-induced loosening without the need for thread-locking compound or secondary fasteners. At 5\/8 inches high and 7\/8 inches across the flats, this nut fits standard 9\/16-18 UNF threaded fasteners and is driven with a standard 7\/8-inch wrench. It is suited for mechanical assembly, HVAC equipment mounting, plumbing fixture installation, and general trade fastening applications where vibration resistance is required.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is appropriate for residential and light commercial applications across HVAC, plumbing, electrical, and general mechanical trades. The 9\/16-18 UNF right-hand thread is a common size in equipment mounting and structural fastening scenarios. Grade 2 steel construction makes it suitable for standard-duty, non-critical fastening tasks. The zinc plating provides a measure of corrosion protection in moderately exposed environments. 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 provides prevailing torque locking action to resist vibration loosening\u003c\/li\u003e\n  \u003cli\u003e9\/16-18 UNF right-hand thread for compatibility with standard inch-series fasteners\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for standard-duty mechanical fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for moderate corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch height and 7\/8 inch width across flats for use with standard tooling\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; does not meet military specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock fastener for any application requiring a 9\/16-18 UNF right-hand thread hex lock nut with nylon insert locking.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 7\/8-inch open-end or box wrench; power-driven installation is not recommended as it can damage the nylon insert and compromise locking performance. Nylon insert lock nuts are typically single-use — once fully torqued and removed, the insert may not retain full locking effectiveness and should be replaced. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly being fastened.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Lock Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-18 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\u003eHeight\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Grade 2 Steel\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: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: R50000018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692553634098,"sku":"R50000018","price":2594.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d2e5448b1d15401d5c9c7148c7d11d5.jpg?v=1788299177","url":"https:\/\/voomisupply.com\/products\/value-collection-r50000018-hex-lock-nut-9-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
