Abstract
An apparatus is provided for removing a fastener from a corresponding aperture defined by a workpiece that reduces or eliminates damage to the fastener and/or the workpiece. The apparatus includes a pulling plug for engaging the head of the fastener, and a drive shaft operably connected to the pulling plug. The apparatus further includes a lever member that is urged into operable contact with the workpiece. In operation, the head end of a fastener is engaged by the pulling plug. Thereafter, the lever member is moved into contact with the workpiece. The drive shaft is then retracted while the lever member continues to be urged into operable contact with and to push against the workpiece without positively engaging the workpiece. As such, the pulling plug is also moved away from the surface of the workpiece to remove the fastener from the workpiece.
