Torx is a type of screw and bolt drive, which looks like a six-pointed star. Screws with a torx drive have an advantage over Philips or Pozidrive screws. There is a better transference of force from the screwdriver or drill to the screw. This decreases the chance of the bit slipping out of the screw head when driving in the screw. As a result, it is easier and smoother to drive in screws.
