Torque screwdrivers with over-torque protection for different applications from series production to maintenance work. With a locking mechanism that prevents adjustment of the torque when in use. The hexagon lock shape prevents rolling away. Setting by using micrometer scale. Profiled light metal handle.
When the set torque is reached the screwdriver triggers and signals clearly (audibly and perceptibly). It is then again immediately ready for use. The trigger mechanism is unavailable for tightening left-handed threads.
Tested to DIN EN ISO 6789.
The guaranteed measuring accuracy of the torque is achieved only once the torque range has been calibrated to DIN EN ISO 6789
