Abstract: Apparatuses and methods are disclosed for extracting broken members, such as bolt and threaded fasteners, from tapped holes. The apparatus includes a shaft having a plurality of stepped regions and at least one engagement edge extending along the shaft. The apparatus further includes a drive portion suitable for mating with a driver, such as a wrench or power tools, to apply torque to and rotate the apparatus around an axis passing through the stepped regions of the shaft. Preferably, the apparatus includes four stepped regions of decreasing cross-sectional dimensions. The two largest cross-sectional regions define the drive portion that is engaged by the driver. The two smaller cross-sectional regions, or engagement regions, define an engagement portion. The cross-sections of the engagement regions are substantially square and defined by four substantially parallel engagement edges extending over the length of the engagement regions parallel to the rotational axis.
