<p>A tool to remove a locked collar locked to the threaded shaft of a frangile fastener, having a collet (20) with gripping means and inner grasping teeth (23) has a segment removed to permit the collet to decrease in size. An outer cylinder (3) with inner threads are sloped contrary to the threads locking the collar to the fastener shaft and a bottom inner tapered portion (7). An inner cylinder (2) with matching threads and torquing means is torqued with respect to the outer cylinder (3) to translate within the outer cylinder, urging the collet (20) within into inner beveled portion of the outer cylinder thereby closing the collet to surround and grasp the locked collar. While the shaft of the fastener is held, further torquing impacts rational force the collar in an opening direction.</p> |
