Factors Affecting
Tightening Torque
The tightening torque is affected by
a wide variety of factors including the
following. After tightening, always check
the torque with a torque wrench.
1) Voltage
When the battery pack becomes nearly
discharged, the voltage decreases and
the tightening torque drops.

2) Tightening time
Longer tightening time results in
increased tightening torque. Excessive
tightening, however, adds no value and
reduces the life of the tool.
3) Different bolt diameters
The size of the bolt diameter affects the
tightening torque.
Generally, as the bolt diameter
increases, tightening torque rises.
