EXTENSIONS CALCULATOR

USING ADAPTERS OR EXTENSIONS

Adapters or extensions should only be used in line with the wrench, as opposed to being at an angle, and the actual torque applied will be greater than the torque reading shown.

To obtain your desired torque reading, use the below calculator by inserting your values in the following order:

  1. Extension Length
  2. Wrench Length
  3. Actual Torque

This program is based on the ideal equation:
ACTUAL TQ = INDICATED TQ x (WRENCH LENGTH + EXTENSION LENGTH) / WRENCH LENGTH

NOTE: We are not responsible for inaccuracies or errors. Please check the output for accuracy before using in a production environment.
