Threaded fasteners that are tightly seated can be removed or installed easily using a tool constructed following the precepts of the present invention. The tool includes a pivot that can be releasably secured to any fixed object close to the fastener to be removed. A lever is pivotably connected to the pivot at its far end, and its near end has a handle for pressing downward on the lever. The drive assembly Is slidable along the length of the lever and can be aligned with the screw or fastener to be turned. The drive assembly includes a bit to engage the fastener, and the lever is used to press the bit tightly into the head of the screw. The drive assembly is rotatable, and maybe turned by a conventional tool such as a socket wrench or a box wrench. In this way, screws which are awkwardly located or are part of equipment that would be damaged by a slipping bit can be readily installed or removed.
