ABSTRACT:
A tool for removing threaded fasteners includes a threaded bracket and a remover having a driver and an engager. The driver has a first threaded section engageable to the bracket and a second threaded section of larger pitch threadably engaged to the engager. A stop limits relative rotation between the driver and engager. The intersection of the threads between the driver and bracket and the driver and engager forcibly engages the engager into the threaded article to be removed and maintains engaging pressure against it as the driver is initially backed out of the bracket.
