Tohnichi QL-N Adjustable Torque Wrench

Capacity 2 / 5 / 10 / 15 / 25 Nm

Small Adjustable Clicker Wrench with Reversible Ratchet

Basic click type torque wrench for various tightening applications. Its 24 teeth ratchet with 15 degree operating range allows usage in space-limited working conditions.

A clear "click" sound by internal toggle mechanism signals tightening completion upon reaching the set torque. Torque setting is easy to adjust by knob and scale.

The lock-structure has been newly-developed. It assures operation in secure, and set-torque remains solidly. The ergonomic resin handle not only covers the large and easy to read scale but it also reduces operators fatigue.

Via optional colour caps differently set wrenches can be identified at a glance.
