Screw Extractor / damaged screw remover
Screw Extractors - purpose and using instructions
A broken bolt or screw may be removed from a hole with a Screw Extractor. First, drill a hole in the broken bolt. The correct drill size to use is shown below and is also stamped on each Screw Extractor. Insert Screw Extractor in the hole and, with a Tap Wrench, turn counterclockwise. The Screw Extractor acts like a corkscrew. It grips into the sides of the drilled hole and removes the broken part on its own threads without damaging the threaded hole.
