How to use a screw extractor

http://www.bobvila.com/articles/screw-extractors/#.Vechx2TBzGc

Stymied by a stripped screw, or a screw without a head? No worries! There’s a brilliant little tool that can help you remove a stubborn screw with ease. It’s known, appropriately, as a screw extractor.

Here’s how it works: First, you use a very small drill bit to bore into the screw. Next, insert the threaded end of the screw extractor into the pilot hole you’ve created. Finally, attach the opposite, square-shaped end of the extractor either to an electric drill or a T handle. When you turn the screw extractor, it digs further into the damaged screw, exerting counter-clockwise force that backs the screw out. Though screw extractors are one of the least costly extras you can add to your toolbox, they often prove priceless if and when you face a fastener that refuses to budge.
