Description
Version:
The special slipping trigger mechanism reliably prevents unintentional overtightening. Desired torque value is easily set and saved as the user can hear and feel the device engage upon reaching the scale value. The 72 fine-pitched teeth enable a low return angle of only 5°.
With 1/4 inch bit holder.
23-piece set incl. torque wrench Safe-Torque A 2.
With 1/4 inch bit holder.
23-piece set incl. torque wrench Safe-Torque A 2.
Advantage:
Torque lock function: The torque function can be switched off – the tool can therefore also be used as a standard ratchet with high release torques and for applications involving defined rotational angles.
Function:
On reaching the set torque value the wrench triggers a clearly detectable deflection and is then immediately ready for use again. The overslip trigger mechanism ensures that the set torque values are not exceeded.
Standard:
Tested to DIN EN ISO 6789.
