Abstract
Head screw with self-tapping screw thread, characterized in that it has a head and a stem, in which stem three main parts are determined, the first being smooth and the second and third being formed by threaded areas according to opposite hands, to the left and right, so that the second part stops the advance of the screw and blocks it in its position, when it comes in contact with the part that is screwed in the screw.
