Wera torque screwdriver. Safe protection against electrostatic charge and associated damage. With a factory pre-set torque value set to the smallest scale value. For all applications, where the same constant torque and repeat accuracy are required. The torque can be changed with an extra tool within the measuring range (re-calibration kit can be ordered with the code number 05137003001). Afterwards you can check the set value using an off-the-shelf torque tester. With quick-release chuck for rapid bit change. Unlimited loosening torque for slackening stuck screws. Multi-component Kraftform handle with hard and soft zones for high working speeds, whilst being easy on the hand. Suitable for bits with a 4 mm Halfmoon drive (Wera series 9) and a 4 mm HIOS drive (Wera series 21).
