Power grip with comfortable easy-grip Haptoprene® surface allows transmission of the required torque with no problems even with wet or oily hands. On reaching the set torque value, the screwdriver can be felt and heard to trigger and is then again immediately ready for use. The release torque is higher than the tightening torque (overload protection). The desired torque is set using an adjustment wheel at the end of the handle. Putting the wheel into the locked position prevents inadvertent changes to the setting. Easy to read micrometer scale, protected against dirt. To take 6 mm interchangeable blades (No. 659920 − 659928).
Tested to DIN EN ISO 6789.
The guaranteed measuring accuracy of the torque is achieved only once the torque range has been calibrated to DIN EN ISO 6789.
