ABSTRACT:
A hand-held tool capable of removing an anchor bolt, such as a molly bolt, from attachment to a wall. The tool of the present invention includes a pair of jaw members which move into gripping relationship onto the exposed end flange of an anchor bolt, following which a lead screw on the tool engages the attachment screw of the anchor bolt and forces the attachment screw inwardly of the wall. This action causes the legs of the anchor bolt to bend and to be straightened and to become sufficiently narrow in transverse dimension so that the anchor bolt can be manually pulled out of the wall through the hole provided therefor. In this way, the tool permits a quick and easy removal of an anchor bolt from a wall without having to damage the wall in any way.
