Bolt Torque Specifications
Checking Bolt Torque
The tables shown give correct torque values
for various bolts and capscrews. Tighten all
bolts to the torque values specified in the
table, unless indicated otherwise. Check
tightness of bolts periodically.
IMPORTANT! If replacing hardware, use
fasteners of the same grade.
IMPORTANT! Torque figures indicated in
the table are for non-greased or non-oiled
threads. Do not grease or oil threads
unless indicated otherwise. When using a
thread locker, increase torque values by
5%.
Note:
Bolt grades are identified by their
head markings.
