Use these torque values when tightening hardware—excluding: lock nuts, thread-forming, self-tap-
ping, and metal screws—unless otherwise specified.
NOTE: All torque values are in foot-pounds (lb.-ft.), except those marked with asterisks (*), which
are in inch-pounds (lb.-in.). To convert lb.-ft. to Newton Meter (Nm)—metric—torque values, multi-
ply the lb.-ft. value by 1.355, or for inch pounds, multiply the lb.-in. value by 0.113.
* Value shown is in pound-force inch (lb.-in.)—inch pounds.
