Description
Version:
Torque wrench without scale. Wrench setting using torque analyser. The trigger mechanism makes unintentional overtightening extremely unlikely. Anti-clockwise tightening by reversing the plug-in head.
Function:
On reaching the preset torque value the wrench triggers a clearly detectable deflection and is then immediately ready for use again. The long-travel indication gives the user an unmistakable signal that the set torque has been reached.
Application:
For controlled tightening of screws to a pre-set torque during batch productions.
Standard:
Tested to DIN EN ISO 6789.
Cutting data:
