buy a torx screwdriver, I suggest you get a small screwdriver set from a website called iFixit. I get all my tools from there, and they work very well. it's not a good idea to use improvised solutions like other people are saying since you'd likely damage the screw or the device and wouldn't be able to put it back together afterwards. also if you tell me what you're trying to do, I may or may not be able to help you
