Atte nti on
Damage to the torque wrench possible.
Ensure the following when using inserts with
square drive on the torque wrench:
– That the inserts are designed in accordance
with the standards.
– That the inserts are of the correct shape and
size for the joint with the threaded connection
which is to be tightened.

STAHLWILLE socket tools guarantee the cor-

rect lever length, possess the necessary accu-
racy of fit in all contact areas and have the
required material strength.

WA RNI NG
Risk of injury due to exceeding
the maximum load bearing
capability of the inserts and
socket tools.
Make sure that maximum load bearing capability
of the inserts and socket tools is not exceeded.
This may be lower than the maximum permissible
torque of the torque wrench.

WA RNI NG
Risk of injury due to incorrectly
mounted socket tools.
Make sure that the socket tools are secured
against pulling off by engaging the retaining pin.

Risk of injury due to incorrectly
set extension.
Make sure that the extension appropriate for the
socket tool is set on the torque wrench.

CAUTI O N
Risk of injury due to internally
produced special tools.
Produce special tools in consultation with
STAHLWILLE only.
