▶ Check the fastener of the threaded rod with a calibrated torque wrench and application of the correct
check torque. In this process, observe the angle through which the fastener can be turned in the
tightening direction.
Result 1 / 2
The fastener of the threaded rod was not turned farther than through the specified maximum angle of
rotation (< 180 °).
The fastener was tightened correctly.
Result 2 / 2
The fastener of the threaded rod was turned farther than the specified maximum angle of rotation (> 180 °).
The fastener was not tightened correctly. The threaded fasteners tightened since the previous check are
to be regarded as faulty and must be checked. Have the impact wrench checked by Hilti Service.
6.9.3 Checking security of the fastener for installation systems
To ensure that the specified pretension as per the approval / operating instructions has been correctly
applied when the "Adaptive" operating mode is used to tighten pushbuttons, the first pushbutton
and the last pushbutton always have to be checked with a calibrated torque wrench. This check of
the applied installation torque has to be carried out immediately after tightening (installation) of the
pushbutton.
The check torque to be applied corresponds to the installation torque specified for the pushbutton in
question; obtain this information from the operating instructions for this pushbutton.
▶ Use a calibrated torque wrench to check the fastener. In this process, observe the angle through which
the fastener can be turned in the tightening direction.
Result 1 / 2
The fastener was not turned farther than through the specified maximum angle of rotation (< 180 °).
The fastener has been tightened correctly.
Result 2 / 2
The fastener was turned farther than the specified maximum angle of rotation (> 180 °).
The threaded fastener has not been installed correctly. The threaded fasteners tightened since the
previous check are to be regarded as faulty and must be checked. Have the impact wrench checked by
Hilti Service.
6.9.4 Checking T-bolts in cast-in anchor channels
To ensure that the specified pretension as per the approval / operating instructions has been correctly
applied when the "Adaptive" operating mode is used to tighten T-bolts, the first T-bolt and the last T-
bolt always have to be checked with a calibrated torque wrench. This check of the applied installation
torque has to be carried out immediately after tightening (installation) of the T-bolt.
The check torque to be applied corresponds to the installation torque specified for the T-bolt in
question; obtain this information from the operating instructions for this T-bolt.
▶ Check the fastener of the T-bolt with a calibrated torque wrench and application of the correct check
torque. In this process, observe the angle through which the fastener can be turned in the tightening
direction.
Result 1 / 2
The fastener was not turned farther than through the specified maximum angle of rotation (< 360 °).
The fastener was tightened correctly.
Result 2 / 2
The fastener was turned farther than the specified maximum angle of rotation (> 360 °).
The fastener was not tightened correctly. The threaded fasteners tightened since the previous check are
to be regarded as faulty and must be checked. Have the impact wrench checked by Hilti Service.
6.9.5 Checking threaded fasteners tightened in the "Tightening" operating mode
▶ At regular intervals, using a calibrated torque wrench and proceeding in accordance with your company
regulations or quality specifications, check that specified tightening torque has been achieved.
