Torque Formulas
- When using a torque wrench-SSTor 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 x [L/(L+A)] |
| kgf-m | kgf-m x [L/(L+A)] |
| kgf-cm | kgf-cm x [L/(L+A)] |
| ft-lbf | ft-lbf x [L/(L+A)] |
| in-lbf | in-lbf x [L/(L+A)] |
A: The length of the SSTpast the torque wrench drive.
L: The length of the torque wrench.
