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.
Always select a drill bit that is slightly smaller than the screw you want to remove.
Attach to the drill
Line the drill bit up with the centre of the screw
Work slowly to drill a hole for the extractor
Place the spiral end of the extractor into the hole you have drilled.
Twist the extractor anti clockwise until you cannot turn it anymore
Twist the extractor with a wrench or drill. Grip the top of the screw extractor with a wrench. Twist it anti clockwise until the screw comes free.
If using a drill, attach the free end of the extractor to the drill, set to rotate in reverse and turn it on to turn the screw anti clockwise
Remove the screw using pliers
