There are a couple of things to try, but it's not always easy. -If you happen to have or can borrow a welder (any cheapo kind will do), tack weld a piece of metal to the head, something you can grip with your hand or a wrench so you can unscrew it. Make sure you have enough room to turn it. -Cut a slot into the head so you can use a screwdriver. -Find a socket (or even a pipe) that will jam onto the sides of the head and unscrew it. Expect it to slip a lot at first but eventually it does work. Sometimes you can jam something like sandpaper between the sides of the head and socket to give it some grip. I use this method all the time to remove frozen rusted screws, or even those with some special head that requires a special tool. This was an old trick used by thieves to steal mag wheels with wheel locks. -Using a metal chisel, put a notch on the side of the screw head, then angle the chisel a bit and hammer it to make the screw turn, following the notch round and around as the screw backs out. This works for any and every stuck screw, no matter how rusted or whatever. And of course, once you have it sticking out a bit, vice grips or a wrench makes the rest easy.
This did not work to loosen one way screws at all ..only works to tighten them
Does not work--watch you tube--buy dremel tool
You use it with a screw gun, you use the appropriate bit for the screw to remove.
