New groove for screw heads, characterized by the fact that the groove has a rhomboidal shape with sharp truncated vertices, and without reaching the edge of the head of the screw, at the bottom of which there is a blind hole, in which fits a lug that emerges from the center of the end of the screwdriver, whose edge also has the rhomboidal shape which, in turn, fits into the rhomboidal slot of the head of the screw which lug together with the faceted sides of the end of the screwdriver prevents accidentally detaching the screw head from the end of the screwdriver.
