◆ Things to remember when ordering

Not available for inspection purposes.

For models with a limit switch designed to prevent human tightening errors, refer to QSPLS/CSPLS/SPLS/RSPLS/SPLS-N.

QSP is preset, so you cannot set torque without a tester. When ordering, be sure to specify operating torque.

Preset style.
The set torque cannot be changed without using a special tool (sold separately), preventing the operator from changing torque by mistake.
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.
The QSP/QSP-MH series are compliant with ISO 6789:2017 starting January 2022. For more information, see the technical data “Initiatives for ISO 6789:2017” at the bottom of the screen.
