Abstract
An improved screw, of the type that has in its head two holes diametral orthogonal to each other, arranged to facilitate the action on the assembly, essentially characterized by having in said head a hole arranged in axial direction and provided with any appropriate section, which extends from the free base of that to the lower plane determined by the expressed diametrical holes, causing an axial emptying, which significantly reduces the length of these holes and the amount of material that must be extracted for the realization thereof.
