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 tighten-
ing torque drops.
