A concentric threaded fastener comprising a body with a starting shape, an ending shape, and at least one continuous surface formed by layers between the starting shape and the ending shape, where the layers are concentric so that each successive layer from the starting shape to the ending shape has local clearance between the layer and a larger adjacent layer and so that each layer forms a plug when it is aligned in an unrotated position, and where each layer is successively rotated about at least one axis to form the continuous surface. A concentric threaded system comprising a concentric threaded fastener and a receiving component comprising an opening with mating continuous surface dimensioned to accept the continuous surface of the concentric threaded fastener so that the mating continuous surface and the continuous surface of the concentric threaded fastener make complete surface contact when the concentric threaded fastener is at a terminal position within the receiving component. |
