Description

Features

  • Pre-Lock Adjustable Torque Wrench
  • Torque set is changed by using a standard hex key to adjust setting on scale
  • This creates a more secure torque setting, in comparison to QL types which have a large knob
  • Suitable for mass production as single purpose with graduation.
  • A clear “Click” sound signals tightening completion upon reaching the set torque.
  • The ratchet head has 24 teeth with a 15 degree operating range, allowing for use in space-limited working conditions.
  • Applicable for international use including the EU region. Compliant with calibration procedures of ISO 6789 Type II Class A.
