Table of tightening torques for bolts and nuts
●
Unless speci
fi
ed otherwise, tighten metric nuts and bolts to the torque below. (When using
torque wrench)
NOTICE
The following items apply to fi ne thread and coarse thread.
●
Apply grease (zinc white B dissolved in spindle oil) onto the nuts and bolts to reduce
the friction coeffi cient. Thrust bolts do not require greasing.
●
Torque tolerance is ±10%.
●
Always use bolts of correct length. The tip of bolts with excessive length may contact
the bottom of the bolt hole, resulting in under-tightening. Bolts with inadequate length
may result in insuffi cient fastening.
●
The torque values listed in the table are intended for general application. If different
torque values are specifi ed for a special purpose, the torque values in this table are not
applicable any more.
●
Make sure the threads are free of dirt or rusts before installation of nuts and bolts.
