TIGHTENING TORQUE
The power required for tightening a bolt
will vary, according to bolt material and
size, as well as the material being bolted.
Choose the length of tightening time
accordingly.
Reference values are provided below.
(They may vary according to tightening conditions.)
Factors Affecting Tightening
Torque
The tightening torque is affected by a wide
variety of factors including the followings.
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.
