Tightening conditions
• The following bolts are used.
Standard bolts: Strength type 4.8
High tensile type 12.9

2) Tightening time
Longer tightening time results in increased
tightening torque. Excessive tightening,
how ever, adds no value and reduces the
life of the tool.
3) Different bolt diameters
The size of the bolt diameter affects the
tight ening torque.
Generally, as the bolt diameter increases,
tightening torque rises.
4) Tightening conditions
Tightening torque will vary, even with the
same bolt, according to grade, length, and
torque coefficient (the fixed coefficient indi-
cated by the manufacturer upon produc-
tion).
