392 Bitholding screwdriver with flexible shaft

External Hexagon
Kraftform

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.

Screwdriving can also be achieved "around the corner" with the screwdriver 392. The flexible shaft allows unfavourably-positioned screw fastenings to be reached. The ideal tool for difficult-to-access screwdriving applications e.g. in the engine compartment of a car.
