Whereas the Torx bits feature a star-like shape, the triple square bits are the opposite. They are simply a trio of interlocking squares all at a 90-degree angle. The two are often mistaken because they share a lot of the same applications. The triple square’s use, however, comes primarily in the automotive world.

Either way, be ready to replace the screw and/or the tool used because of damage. Your best bet is just to get a Torx key.
Why do Torx screws exist?
The Torx design was introduced in the 1960s as a replacement to Phillips or slot style screws/driver combinations. Where the Phillips/Slot style screws were designed to prevent over tightening allowing the tool to slip beyond a specific torque, the Torx was designed to prevent slipping and reduce damage to the tool.
What is the difference between Torx and Torx Plus?
The Torx Autosert feature guides the driver bit accurately into the recess creating a self-centering engagement action. Torx Plus is designed for high torque transmission. This means that higher torques can be used to securely tighten fasteners without incurring additional wear and tear on the tools.
Can you use hex instead of Torx?
We actually don’t recommend using your torx wrenches in place of a hex key or Allen wrench. With that being said, torx size, T9, won’t doesn’t really work with any of the SAE hex sizes. However, it’s actually a perfect match for metric size, 2.5 mm.

Star drives / screws or Torx as they are commonly known are often used in situations where a certain amount of security or tamper resistance is desired and because of the make up of the star allows a bit more torque than a Phillips and a lot more than a Slotted.
Is Torx better than square?
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.
