11.3 Bolt Torque
IMPORTANT! If you replace hardware, use fasteners of
the same grade.
IMPORTANT! The torque specifications in these tables
are for non-greased or non-oiled threads. Do not grease
or oil fastener threads unless otherwise indicated. When
using a thread lock, increase the specified torque 5%.
Bolt grades are identified by the marks on the
bolt head.
The bolt torque specification tables provide the correct
torque settings for common bolts and capscrews. Tighten
all bolts to the torque that is specified in the table, unless
otherwise indicated. Check the bolt tightness periodically.
