Abstract: A nut device and corresponding tool of such shape to aid in the ease of removal from a threaded bolt, stud, or the like. The principal intended use of this invention is for fastening the wheels of a vehicle to the vehicle's axle, but could easily be applied to any threaded fastening system. The nut and subsequent tool fit together in such a manner that prevents slippage or dislodging of the tool from the nut while in operation. This problem is common for conventional hexagonal-type threaded fastener and tool systems that are typically used on wheels of vehicles.
