Description
Version:
One-armed torque wrench without a setting scale. Set the desired torque value with setting tool No. 657452 size 1 in conjunction with a suitable test device.
With built-in reversible ratchet with ejector − for left-hand and right-hand tightening. Torque wrench, only right-hand triggering.
With built-in reversible ratchet with ejector − for left-hand and right-hand tightening. Torque wrench, only right-hand triggering.
Function:
On reaching the set torque value the wrench triggers giving a “signal”(audible and perceptible) and is then immediately ready for use again.
Application:
For controlled screw tightening etc. to specified torques in batch productions.
Standard:
Tested to DIN EN ISO 6789.
Accuracy:
±2% of the set value.
