Mayhew Pro D 13/16 in. S 1-3/8 in. Screw Extractor

Used for removing broken or seized screws. With a 3/4 body size and hardened steel edges this extractor is designed to handle some of the toughest jobs. The screw is first drilled out to the proper diameter for that extractor. The extractor is then inserted into this hole and turned counter-clockwise using a tap wrench. As the extractor is turned, the flutes on the tool dig into the screw, causing it to lock tightly and apply sufficient torque to remove the screw.
