First, by design, Torx are less likely to strip out when compared to a hex because of the way the load is distributed and applied between the tool and the hardware. Second, due to the this improved load handling, the height of the screw head can be reduced.
What is the point of Torx screws?
Torx screws are typically used in vehicles, motorcycles, bicycles, computer systems, hard disk drives and consumer electronics. The unusual star-shaped head makes them far more secure than regular flat-head or cross-head screws and allows higher torque transmission so screws and bolts can be tightened more securely.
What advantage do Torx and Allen screwdrivers have over right angled versions?
Torx type screws, allow you to apply more torque. Leting you fasten the screw much tighter. With out the danger, of striping the head. Also, it lets the manufacture gain a little security.

Screw drive types are one of the oldest standards contests in woodworking. … A short version of the answer is: The Torx allows higher torque transmission and better screwing ergonomics, but should preferably be used with a torque-limiting clutch to prevent overdriving or overloading the bit and the screw.
Are star drive screws better?
Star Drive can take handle more torque than Square Drives and are therefore more resistant to ‘camming’. This makes drivers last longer. As a result of the higher torque capacity, generally Star heads are in better condition once the screw is set, making removal easier if ever necessary.

Phillips head screws were purposely designed to cam-out to prevent over-tightening. Torx heads were designed to resist cam-out, thereby offering improved torque transfer between the driver and the fastener. This feature also reduces wear on driver bits.
Why do people use star screws?
The Star (also known as Torx) has a six-point, star-shaped drive that was developed mainly to enhance tamper resistance and ensure snug fits. The star design drivers cut down on the risk stripping the screw heads, slippage, or cam-outs, with tight, specific fits.

Although it fell off the bit and wobbled, my son-in-law and I liked Torx® better than the other two screws because of its stronger torque. … The Torx® driver bit we used for the #9 did not fit on the #8 screw, meaning after a long day, I had to take a trip to the hardware store!
Is Torx better than Robertson?
Both seated firmly in the screw and performed well. The Torx are actually fractionally quicker to seat on the screw. This make sense when you consider that there are six points on a torx, versus four on a robertson. So there are more positions where the torx screwdriver will just slip into place.
Why are decking screws Square?
Many times, stainless steel deck screws have a square drive because they are softer then other screw materials. The square drive provides a more positive bit engagement making it harder for the heads to strip out. … Using an impact driver also helps to drive screws without stripping the heads.
