![]() TORX screw, the funny looking screw drive. Same design and sizing as square recess, but includes a centered tamper-resistant pin. Commonly found in two sizes: Square #2 and #3. Square recess is being used more and more as they are very resistant to cam-out, which is a fancy way of saying the tip of the tool does not slip out and mar the screw head very easily. It looks a lot like a Phillips screw head, but it includes 4 more contact points. This screw head isn’t seen very often in the U.S.A., though it is very common in Europe. This screw is not used in high torque applications as the design is not very strong and the bits cannot be manufactured to high strength specifications.Ī combined Phillips and square recess drive. Same shape and sizing as Phillips, but the screw includes a tamper-resistant pin in the middle. Not very common, but when you need one, you need one. This screw drive type is very popular – and again, you find them in a very wide range of applications. You find these everywhere, though the practice of using screws with slotted drives is on the decline because the screwdriver slips out of the slot, particularly when you are applying heavy torque to really tighten down (or loosen, for that matter) these types of screws. I know some of these look the same (can you tell the difference between a Pozidriv and a Phillips from 10 feet away?) but they are not – and you risk damaging the screw and ending up taking a lot of time to extract it if it gets damaged. Always use the right driver for the screw head you are working on. ![]()
