A hand tool for driving a fastener is provided. The hand tool includes gearing that interconnects a splined socket to a rotatable or trigger actuator and increases a rotational speed of the splined socket relative to the actuator. The hand tool may include a power tool receiver 38 or an independent motor to drive rotation of the splined socket to advance or retract a fastener from a threaded shaft. By increasing the speed and conserving rotational inertia, the hand tool reduces the time to secure a fastener on a threaded shaft. A rotatable nut is provided. The rotatable nut can slideably orient along a first axis and threadedly orient along a second axis to fasten to an adjacent surface.

A tool for installing and removing a highly-torqued fastener that allows an individual to easily and efficiently remove or install a bolt from or onto a crankshaft pulley or similar assembly. The tool includes a prismatic housing, a worm gear assembly, a torque input, and a torque output. The prismatic housing is a rigid structure that is used to conceal and protect the worm gear assembly. The torque input allows an individual to manually provide the torque force through the use of a ratchet tool, motor drive, or other similar tool. The torque output is able to receive a bolt socket in order for the tool to provide the torque force to a bolt of a crankshaft pulley. The worm gear assembly is used to transfer the torque force from the torque input to the torque output. Thus, the tool can easily remove or install a bolt.
