We’ve all stripped a couple of screws in our day. And it normally isn’t a big setback—until you need to unscrew it, that is. So the next time you’re in this situation, try a rubber band for a screw grip.
Place a wide rubber band in between the screwdriver and the stripped screw head, then apply hard, but slow force as you turn the screw. The rubber band should grip the stripped screw head and allow you to extract the screw.
