Using Extensions
Depending on the type of extensions used, you may
need compensate for added leverage by using a
lower torque setting to reach the true torque setting
applied to the fastener.
Note:
Compensation is only needed if the total
length of the torque wrench is extended. Typical
socket extensions that remain perpendicular to the
ratchet head do not change the length of the torque
wrench, and therefore, do not change the torque
applied to the fastener.

Typical Fastener Torque Settings
The charts below offer average torque recommen-
dations for different fastener sizes. Exact torque
settings are defined by fastener material type and
plating, lubrication, surface finish, and whether or
not the parts being fastened have gasketed joints.
Always follow the manufacturer’s torque recommen-
dations for your particular fasteners. Regardless of
any torque recommendations,
NEVER exceed the
maximum torque setting on your wrench.
