? Why does Wera manufacture adjustable

Kraftform torque screwdrivers?

Many screws – particularly in assembly and maintenance applications
– have to be tightened with controlled torque to ensure the
dependability of the screw connection and/or to avoid damage to the
screw or work piece. Wera’s adjustable torque screwdrivers are the
ideal tool for this. They feature a torque range of 0.3 Nm to 8.8 Nm,
two different handles, measurement accuracy of ± 6 % and
Rapidaptor technology for rapid bit change.
