Abstract
Perfeccionamientos in threaded metal fasteners, characterized in that these are provided with a recess adjustment of the drive tool, punched at the upper end thereof; said recess contains a central cavity and a series of slots in the peripheral wall of said cavity, equiangularly spaced around it; each slot has a pair of side walls and is arranged to receive between the two side walls thereof, a correspondingly shaped portion extending radially outwards, of a driving tool coupled inside the recess; the grooves of the recess are in number four extended radially with respect to the central cavity, and symmetrically spaced around it, in such a way that the recess is of an essentially cruciform type; furthermore, the side walls of the four radially prolonged grooves of the recess, are practically vertical and during the formation of the recess by means of the appropriate punch, part of the metal of the upper end of the fastener moves in such a direction as to compensate for the natural detachment of the metal of each of the four side walls of at least four grooves of the recess equiangularly spaced apart, such that at least in said side walls of the grooves, the recess fits perfectly in all the depth of said side walls of the grooves. grooves, from the mouth of the recess to the bottom thereof, with the intended shape of the punch forming the recess.
