Torque Screwdriver


Features no scale on the body of the tool.

  • Because there are no scales, a torque tester and a specialized adjusting or thrust ring tool are required to set the torque value.
  • Ideal for mass assembly applications where one torque setting is dedicated to one tool.
  • Since this type requires additional equipment to change the torque, it prevents the torque setting from being changed by unauthorized personnel.
  • Preset styles have lower maintenance costs compared to other types of torque tools due primarily to the fact that there is no scale to maintain and calibrate.
