Tightening torque will vary, even with
the same bolting material (e.g. steel),
accord ing to the surface finish.
Torque is greatly reduced when the bolt
and nut start turning together.
5) Socket play
Torque is lowered as the six-sided configu-
ration of the socket of the wrong size is
used to tighten a bolt.

6) Switch (Variable speed control trigger)
Torque is lowered if the unit is used with
the switch not fully depressed.
7) Effect of Connecting Adaptor
The tightening torque will be lowered
through the use of a universal joint or a
connecting adaptor.
