Description
Version:
The special slipping trigger mechanism reliably prevents unintentional overtightening.
Torque wrench without scale. Wrench setting using torque analyser.
With integral ratchet
Torque wrench without scale. Wrench setting using torque analyser.
With integral ratchet
Advantage:
Precision triggering mechanism facilitates working in inaccessible places.
Function:
On reaching the set torque value the wrench triggers a clearly detectable deflection and is then immediately ready for use again. The special trigger mechanism ensures that the set torque values are reliably achieved, but not exceeded.
Application:
For medium to larger batch productions.
Standard:
Tested to DIN EN ISO 6789.
Accuracy:
±6 % of the set value.
Cutting data:
