Frequently Asked Questions

How do you use a torque wrench?

  • Adjust the handle and set it to the desired torque level.
  • To lock it in place, use the tightener at the end of the handle.
  • Slip it over the socket / nut / bolt and tighten it clockwise.
  • When finished, reset the handle's settings to 0 and store it somewhere safe.

How do you set the torque on a torque wrench?

  • Turn the knob at the wrench handle's end clockwise.
  • This tightens the wrench and sets the torque level on the wrench.
  • If you need to re-adjust the torque, loosen the knob and turn the handle to the desired torque.
