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.

מאפייני המוצר
Flexible shaft
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.
Kraftform
Rapid hand repositioning
The hard materials used for the handle ensure rapid hand repositioning without any danger of the skin “sticking” to the handle. The surrounding hard zones with large diameters glide like wheels through the hand.
Large contact area
The large contact area – with particularly high friction to the soft zones – results in high torque transfer without any bruising from the edges.
Identification marking
The screw profile and tip size identification markings on the handle make it easier to find the right screwdriver in the tool case, or at the workplace.
Non-roll feature
The hexagonal non-roll feature prevents any rolling away at the workplace.
