17.1 Tightening torques for screws with metric screw threads with and without wedge lock

washers

Notice

In the case of galvanised screw plugs and screw plugs made of stainless steel the inner thread and
outer thread have to be greased thorough before mounting in order to prevent threads from seizing.

Notice

The manufacturer recommends tightening screws with wedge lock washers according to the table
three times after another with the same tightening torque.
