ABSTRACT:
A calibrated torquing wrench that can be set to a predetermined value and upon reaching this torque by the rotation of the wrench will release the gear (28), spring (34) engagement and will allow the wrench to free-wheel for a small angle before re-engagement of the gear (28) and spring (34). The wrench will then endlessly rotate and repeat the predetermined value without exceeding the setting.
