SHOP TALK!!! how to defeat a stripped screw head without losing your mind<br /> by [[Typewriter Justice]] on Youtube

To help remove a stripped screw head, hit it with Kroil or a similar penetrant first. Then with a screwdriver, punch or similar tool, give it purchase on the right hand side somewhere and give it a nice whack with a hammer. This should turn the screw enough to move things along.
