Enter the actual torque applied to the nut, the normal length of the wrench and the extended length to calculator the torque setting of the wrench.

## Torque Wrench Extension Formula

The following formula is used to calculate the torque setting of an extended wrench.

T1 = T2 * (L1/L2)

- Where T1 is the torque setting of the wrench
- T2 is the torque applied to the nut
- L1 is the normal length
- L2 is the extended length

## Torque Wrench Extension Definition

A torque wrench extension is defined as a wrench that has been extended past it’s normal length to achieve greater torques.

## Torque Wrench Extension Example

How to calculate the torque setting on a wrench extension?

**First, determine the torque applied to the nut.**Calculate the total torque applied to the nut. This would be the force times the extended length.

**Next, determine the normal length.**Measure the original length of the wrench.

**Next, determine the extended length.**Measure the extended length of the wrench.

**Finally, calculate the torque setting.**Calculate the torque setting of the extended wrench using the formula above.

## FAQ

**What is a torque wrench extension?**

A torque wrench extension is the extension of increase in length of a torque wrench that is done in order to achieve higher torques.
