Abstract
Improved corresponding screw and tool, essentially characterized in that the screw is provided on its head with an advantageously slightly truncated-pyramid cavity, while the tool has a coincident configuration at its operative point, so that the four peripheral planes thereof are supported on the corresponding planes of the cavity and the rotation and penetration of the screw is facilitated.
