Version:
Torque wrench, adjustable using micrometer scale, with protection against accidental changes to the setting. With reversible ratchet head and square drive for sockets.
Units of measure: Nm.
Function:
On reaching the set torque value the wrench triggers giving a “signal” (acoustic and perceptible) and is then immediately ready for use again.
Application:
For medium and large 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:
The guaranteed measuring accuracy of the torque is achieved only once the torque range has been calibrated to DIN EN ISO 6789.
