Relationship between bolt
tightening time and torque
Tightening torque varies with bolt tighten-
ing time as illustrated in the following figures.
(Figures show reference values. Actual per-
formance varies with tightening conditions.)

Factors affecting bolt tightening
torque
Bolt tightening torque varies due to factors
described below.
1) Tightening time
Longer tightening time results in increased
tightening torque. Excessive tightening,
how ever, adds no value and reduces the
life of the tool.
2) Bolt
•Bolt diameter: Tightening torque gener-
ally increases with bolt diameter.
•Torque coefficient (indicated by the bolt
manufacturer), grade, length, etc.
3) Battery pack charge status
•Tightening torque decreases as the bat-
tery is discharged.
•Tightening torque decreases rapidly as
the battery nears the end of its charge.
(The product’s automatic power-off
function will engage once the battery’s
charge is exhausted.)

4) Other
•Bit and socket condition: Material,
amount of play, etc.
•Use of a universal joint or socket adapter
•User: Manner in which the tool is applied
to the bolt, strength with which the tool is
held, manner in which the tool’s switch
is engaged
•Condition of object being tightened:
Material, seating surface finish.
