Installation is straightforward with a standard 13/16″ socket, and the precision‑cut, burr‑free threads ensure a smooth, secure fit that resists loosening under vibration. The set includes ten nuts, offering ample quantity for routine maintenance, replacements of worn or stripped fasteners, or for keeping a spare supply on hand. Whether you are servicing a trailer hub, a utility wagon, or any wheel that requires a 1/2″‑20 thread, these lug nuts deliver stable performance and a long service life.
