Abstract
A torque screw having a screw with a head and a threaded shaft, a knob having a central longitudinal axis coaxial with the screw and a one-directional ratchet disposed between the knob and the screw that engages to allow the screw to be disengaged in a counter-clockwise direction using the knob, and engages when rotated in a clockwise direction to a predetermined torque value. Once that predetermined torque value is reached, the ratchet is caused to slip such that the knob turns relatively freely with respect to the screw.
