A threaded nail, characterized in that the thread does not start with a sharp point, but the tip of the nail remains unthreaded and then the threads are all of the same diameter, so that a cut made by the longitudinal axis of the nail gives a non-increasing succession of elements in the form of truncated cones of inclined bases.
