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 SPECIFICATION
| 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 SST past the torque wrench drive.
L: The length of the torque wrench.
