Note :
Calibration is only possible for right-hand tightening. The guaranteed measuring accuracy of the torque is achieved only once the torque range has been calibrated to DIN EN ISO 6789.

Standard :
Tested to DIN EN ISO 6789.

Application :
For medium to larger batch productions.

Version :
Handy and very compact one-armed torque wrench, adjustable by scale and self-triggering. Extremely high repeat accuracy, since high quality materials are used throughout. Wearing parts, such as compression springs, are specially pre-treated and sorted. Reversible ratchet for left-hand and right-hand tightening. Acoustic and perceptible “click effect” ensures particularly easy use and accurate setting of the desired torque. Basic tool with square plug-in socket (without plug-in head). Suitable spare jaws No. 657582 - 657950. Units of measure: Nm

Function :
The wrench triggers giving a “signal” (clearly audible acoustic tone and noticeable vibration) and afterwards is immediately ready for use again.

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
