The torque screwdriver was developed to carry out the screwdriving process precisely and reproducibly with the correct tightening torque. With the torque screwdriver, the torque (0.05 to 0.6 N m) can be selected and preset. It has a 6-edge bit holder 6.3 mm (¼ ") with a clamping ball. The torque can be adjusted to the desired size using a knurled screw. The set value can then be locked. The screwdriver has a total length of 105 mm. A useful accessory is an extension (110 mm) and a bit adapter from 6.3 mm to 4 mm bits.
