Abstract: An extractor tool may include a driven end configured to receive drive power from a driving device, a drive end configured to interface with a fastener, and a body portion extending between the driven end and the drive end about an axis of the extractor tool. The drive end may include a fastener engagement recess which may extend into the body portion and coaxial with the body portion. The fastener engagement recess may include a plurality of engagement ribs that may be configured to engage with the fastener such that the fastener is drivable in either a clockwise or a counterclockwise direction while avoiding contact with corner portions of the fastener. The extractor tool may further include a magnet carrier assembly which may be operably coupled to a magnet which may be configured to engage with the fastener at different depths of the fastener engagement recess.
