*If the slot of a round-headed screw is stripped, file two flat edges in it. Then, it can be turned with an adjustable wrench. Or, use a hacksaw to file a new slot at a right angle to the existing one. Depending on the size of the fastener, using a Dremel tool or a die-grinder with a fiber wheel, carefully grind a large, deep slot in the head of the fastener, and before it cools, use a large screwdriver to remove the fastener.

*Drill and tap the bolt to run another, smaller bolt down the center. A bit about half the diameter of the headless, stuck bolt is usually sufficient. Use a jam nut on the small bolt and lots of penetrating oil.
