any torque loss of the bolts exceeding 30 per cent of the nominal torque measured in the closing direction

The computing part (19) estimates tightening torque Tave based on the estimate value of the first tightening torque (T1) or the second tightening torque (T2).

The loosening torque is greater than the tightening torque because of the asymmetric profile of the lobes.

The rotatable member includes at least one manual tightening device or mechanism (30) for effectively increasing the manual tightening torque.

To provide an indication of torque, a rotor body is supported coaxially within the driver member.

In this respect the torque while screwing the sensors into the tissue of the patient is limited at least to a maximum, while ensuring at the same time that the torque is kept to an indispensable minimum.

The appliance is designed so that the tightening torque of the threaded body (5) is limited.

The torque wrench (W) is provided with: a wrench body having a tightening part (10), a head (21) whereon the tightening part (10) is provided, and a handle (22); and a load cell (30) that detects the tightening torque.

Thereby, since the necessity for control of tightening torque can be eliminated and the assembling operation can be simplified.

In order to lower torque applications, you may use the “Speed Zone”.

The computing part (19) stops driving the motor (2) when the estimated tightening torque Tave exceeds a set value Tset.

The tightening torque of the hexagon bolt must not exceed 15Nm.

The hard member is peeled off from the brittle member with a force for raising the frame, i.e., with the specified torque.

The computer (40) determines whether or not the tightening torque is the prescribed value and displays the results of the determination.

The worker adjusts the tightening torque of the torque wrench (10) so as to fall within the range of the prescribed value.
