A screw extractor is a tool for removing broken, damaged or seized screws. They can be driven manually using adjustable spanners or vice grip pliers or by using a hand-held power tool. Screws can break, rust or become stripped and need to be replaced. This brings any work or project to a halt. The easiest way to remove the screws before replacing with a new one, is to use a specialist tool such as a screw extractor. The screw extractors are similar to a screw but have a reverse thread.
