Torque setting by a built-in handle

Application

  • For various tightening operations. Applications from 0.4 to 2800 N・m.

Features

  • Basic shape of a torque wrench for tightening operations
  • 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.
  • Torque setting is easy to adjust by knob and scale.
  • With QLE550N2 to QLE2800N2 models, the built-in torque adjustment handle makes torque changes easy even without a special-purpose tool.
  • QL2N to QL25N5 models have a resin grip with a large, clear built-in scale.
  • QL50N to QL280N models have a resin grip, while the QL420N has a knurled metal handle.
  • QLE550N2 to QLE2800N2 models have an extension handle that separates from the body for compact storage.
