Tightening torques for shaft bolts
(Metric ISO Standard Thread)
The values for tightening torques
shown in the table are valid only for
shaft bolts with metric ISO- standard
threads and head support surface
dimensions in accordance with DIN
912, DIN 931 and DIN 933. These
values are also valid only for light or
unoiled, untreated surface as well as
for use only with torque-indicating
wrenches and force limiting tools.
