Torque Formulas

When using a torque wrench–SST or equivalent combination, the specified torque must be
recalculated due to the extra length that the SST or equivalent adds to the torque wrench.
Recalculate the torque by using the following formulas. Choose the formula that applies to
you.
Torque Unit Formula
N·m N·m × [L/(L+A)]
kgf·m kgf·m × [L/(L+A)]
kgf·cm kgf·cm × [L/(L+A)]
ft·lbf ft·lbf × [L/(L+A)]
in·lbf in·lbf × [L/(L+A)]
A
The length of the SST past the torque wrench drive.
L
The length of the torque wrench.
Vise
When using a vise, put protective plates in the jaws of the vise to prevent damage to
parts.
