The 837 i RA bladeholding screwdriver with ratchet functionality

The integrated ratchet with fine toothing (40 teeth and a return angle of 9°) eases and accelerates screwdriving without having to reposition the tool.

Rapid screwdriving

The ratchet mechanism also allows fast "spinning" while screwdriving.

Individually tested

The individual testing at 10,000 volts, in accordance with IEC 60900, ensures safe working with loads up to 1,000 volts.

Kraftform

The basic idea for the prototype of the Kraftform handle – that the hand should dictate the design – has, right through to today, proved to be correct. In cooperation with the internationally recognised Fraunhofer IAO Institute, Wera developed a screwdriver handle designed to match the shape of the human hand as long ago as the 1960s. After a long development phase, the Wera Kraftform handle was launched to the market in 1968. It has been optimised through the years with new technologies, but has kept its proven shape. After all, the human hand has not changed either.
