Abstract
Improvements in threaded fasteners, characterized in that they have an adjustment recess with the corresponding tool, prolonged inside its upper end and along its longitudinal axis, and comprising a central part and a series of angularly separated grooves, radiating from that; the wall of the central part between each pair of mutually adjacent grooves, is prepared to provide a prolonged recess from the mentioned upper end towards the bottom of the recess; the recess is laterally limited by adjustment surfaces with the tool, generally axially prolonged; the recess is decreasing in cross section downwards.
