Professional Applications & Engineering Value
This 5/16"-24 UNF locknut delivers critical vibration resistance where conventional fasteners fail. The distorted thread technology creates consistent interference along the mating thread, maintaining clamp load in high-cycle applications such as machinery, automotive assemblies, and electrical enclosures. Manufactured from zinc-plated steel, it provides essential corrosion protection while maintaining Grade 2 strength for structural integrity. The fine thread pitch offers superior adjustment precision compared to coarse threads, making it ideal for applications requiring exact positioning and minimal backlash. These engineering features combine to solve common industrial challenges of fastener loosening, material degradation, and maintenance frequency.
Specification Summary & Compliance
This locknut features 5/16"-24 UNF fine threads with Class 2B thread fit for standard commercial tolerance. The external hex drive measures 1/2" across flats with a height of 17/64". Manufactured to industrial standards with distorted top-lock thread technology and right-hand thread direction. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial markets.
