Abstract
Six lobes of a nut have axial surfaces falling on six tangent cylinders of equal radius and having axes lying on a right cylinder concentric with the axis of the nut. The surface of a second concentric right cylinder having a radius greater than the first defines furrows between the lobes. Successive lobes are tangent to an imaginary flat surface and the furrows are spaced away from the surface inside it.
