A torque wrench includes an elongated body, a head, and a cantilever beam. The body extends longitudinally from a proximal end to a distal end and includes a channel extending therethrough. The distal end includes an opening extending laterally therethrough along a central axis. The head is rotatably received within the opening at the distal end so that the head is rotatable about the axis. The head includes a gear cam defining teeth about a periphery thereof and an engaging portion sized, shaped, and configured to engage a corresponding engaging feature of a fixation device. The beam is housed within the channel such that a distal tip is received in a space between adjacent teeth. The beam bends when a torsional force applied to the head exceeds a predetermined limit so that the cam rotates about the axis and the distal tip slips from the space between the teeth into an adjacent space.
