* By design, Torx head screws resist cam-out better than Phillips head or slot head screws
* Where Phillips heads were designed to cause the driver to cam out to prevent overtightening
* Torx heads were designed to prevent cam-out
* The development of better torque-limiting automatic screwdrivers for use in factories allowed this change
* The manufacturer claims that this combination can increase tool bit life by ten times or more
* Rather than rely on the tool to slip out of the screw head when a torque level is reached, which risks damage to the driver tip, screw head, and/or workpiece, torque-limiting driver designs achieve a desired torque consistently
