BOLT TORQUE REQUIREMENTS
The tables shown below give correct torque values for various bolts and capscrews. Tighten all bolts to the torques specified
in chart unless otherwise noted. Check tightness of bolts periodically, using this bolt torque chart as a guide. Fasteners
should be replaced with the same grade. Tighten serrated or center-lock nuts to the full torque value.
Do not use these values if a different torque value or tightening procedure is given for a specific application. Torque values
listed are for general use only.
Torque figures indicated at left are
valid for non-greased or non-oiled
threads and heads unless other-
wise specified. Therefore, do not
grease or oil bolts or capscrews
unless otherwise specified in this
manual. When using locking ele-
ments, increase torque values by
5%.
* Torque value for bolts and
capscrews are identified by their
head markings.
