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 top 
of the bolt head.

These bolt torque specification tables give 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.
