Torque screwdrivers are special tools that are used to tighten screws to a precisely defined torque. This is particularly important in applications where the correct tension of the screw connection is crucial to prevent damage caused by over- and under-tightening. The ESD versions offer optimum protection against electrostatic discharge. VDE-safe versions are also available.
Wiha offers SlimBits with a shank Ø of 6 mm to reach deep-set screws. The standard interchangeable blades have a shank Ø of 4 mm. Torque screwdrivers are available in manual and electric versions - individually or as a set.
