Intro: How to Unscrew a Stripped Screw
This works for most screws with a stripped head or security bolts that you don't have the right tool for. Just grab a center punch and a hammer then center punch the side of the screw. When you have a big dent then start hitting the center punch on an angle to get the screw moving. Once its moved 1/2 a turn or so you can undo the screw with pliers or your fingers.
