Removing Stripped Screws

They are different types of screw extractor bits that you can buy in many hardware stores.  Sometimes you don't need to use one of these bits.  Often, I place a screwdriver into the stripped slot.  I give the top of the driver a couple good raps with a hammer to lodge it in the screw.  By doing this you can get the leverage you need to turn the screw out.  If you do have to use a screw extractor bit heres how..... Drill a very small pilot hole into the screw and then use a reverse-threaded screw extractor bit.  Sometimes the screw is so mangled nothing works.  Try getting to a point where you can fit some needle-nose plyers around the screw.
