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:
Legend for drawing and formula:
l1 = Lever length without plug-in head
l2 = Adjusted reference dimension on the torque wrench
l3 = Lever length including factory calibration reference dimension
l4 = Reference dimension of the plug-in head
L = Total length of the tool
T1 = Torque to be set
T2 = Specified torque
Note:
Suitable spare jaws No.
