5.10 Checking threaded fastener

5.10.1 Checking the security of stud anchors

Note
To ensure that the specified installation torque as per the approval /
operating instructions has been correctly applied when the "Adaptive"
operating mode is used to tighten stud anchors, the first anchor and
the last anchor have to be checked with a suitable, calibrated torque
wrench. This check of the applied installation torque has to be carried
out immediately after tightening (installation) of the stud anchor.
▶ Use a suitable, calibrated torque wrench to check the tightening torque
applied to the fastening element. In this process, observe the angle
through which the fastening element can be turned in the tightening
direction.
