Ultimate Screw Idea

This is the idea of a screw or bolt with some new features that might improve its performance.
It has an external and internal torx head. The best possible shape of the exterior part of the head in order to keep an approximately constant thickness while having an internal torx head, is just an external torx head.

The section of the screw thread closest to the head has to bear more load than the tip, where there are just a few threads pulling the screw. Therefore, the load-carrying section of the screw can be much smaller near the tip than near the head, and a screw with a conical longitudinal hole can support the same load while being lighter. Also, the internal tube could provide some grabbing feature similar to that of Robertson screws, but only for screwdrivers that intend to do so, with a tip similar to TTAP. The grabbing feature is very useful when working by hand, but it's detrimental for machine use. These screws can be used in both situations, allowing reusability of screws in
