Torque Wrench Extension Calculator

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?

  1. 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.

  2. Next, determine the normal length.

    Measure the original length of the wrench.

  3. Next, determine the extended length.

    Measure the extended length of the wrench.

  4. Finally, calculate the torque setting.

    Calculate the torque setting of the extended wrench using the formula above.
