Design: Power handle with skin-friendly elastomer coating enables the required torque to be transferred without any problems, even with wet or oily hands. When the set torque is reached, the screwdriver releases audibly and perceptibly and is immediately ready for use again. The loosening torque is higher than the tightening torque (overload protection). The desired torque can be infinitely adjusted using a torque tester (no. 654300 - 654460) and a hexagon screwdriver SW 5 (not included in the scope of delivery). Note: The guaranteed measuring accuracy of the torque is only guaranteed from the calibrated torque range in accordance with DIN EN ISO 6789.
