Abstract
A new screw system, characterized in that the shape of the profile of the screw thread is variable along its path; together, or not, with the variation of the inclination or weight of the same fillet. This makes unnecessary the previous use of cores to screw the drill in which they are made to penetrate, as well as the subsequent use of locknuts to guarantee their correct position when there are vibrations.
