Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
204 words
A nut and mating tool head for mechanical fastening to a threaded stud, said nut being operable by said mating tool head, the nut comprising of: a) a rigid circular main body with a threaded hollow center b) said main body built with a plurality of rigid radial arms extending therefrom each with rounded outer surfaces c) said radial arms each having unparallel rigid interior flat surfaces between the main body and said arm's rounded outer surface d) said unparallel rigid interior flat surfaces of each radial arm oriented at an angle that when projected, intersect at the center of the circular main body the mating tool head comprising of: a) a plurality of teeth or projections matching in plurality the nut's radial projections b) a hollow center to allow a snug fit over the nut's main body c) said plurality of teeth each having circularly rounded interior and exterior surfaces d) the plurality of teeth each having unparallel rigid flat surfaces between said rounded interior and exterior surfaces e) said unparallel rigid flat surfaces of each tooth oriented at an angle that when projected, intersect at the center of said hollow center f) the plurality of teeth built integrally with a rigid body.
Claim 2
Dependent Claim
