ABSTRACT:
The apparatus of the present invention comprises a tool having a threaded member which is characterized by a cylindrical shaft or spindle with a surrounding body or handle. The shaft and body are operably engaged by means of a series of magnets in the spindle and the body, and the operable engagement releases once the torque force on the threaded member exceeds the magnetic force between the body and the spindle. In the method of the present invention, the user can calibrate and adjust the torque limit of the assembly by attaching a calibration bar of predetermined length to the threaded member and then rotating the tool over a scale such that the calibration bar contacts the surface of the scale. The user can then adjust a set screw which alters the length of the shaft and alters the magnetic force between the body and the spindle and correspondingly alters the torque limit of the tool to a desired level.
