FAQ

Use Our Calculators

Norbar has devised easy-to-use online calculators that support the correct application of torque in three key areas:

  1. Unit conversion to assist international measurement definitions.
  2. Torque extension for setting correct values
  3. Torque tension to identify precise levels of torque to be applied for individual applications.
