3. THREADED CONNECTIONS
3.1 TIGHTENING TORQUES
The tightening torques in the table below are
standard torques and only apply to dipped
threaded connections.
The property codes are stamped on the nut and
bolt, except on the clamping flange bolt. The
clamping flange bolt is recognised by a
constriction between the hexagonal bolt head
and the flange. This constriction is absent in
standard flange bolts.
