The Torx screwdriver is much like the Phillips head model only that it uses a six-pointed star shape in its head. These drivers also come in various sizes â from 1 through 100 â with the smallest measuring around 0.031 inches and the largest measuring around 0.871 inches.
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.
