The right or left rotation can be variably adjusted by the integrated switching lever. The combination with the included extensions allow them to conveniently reach deep-set screws and nuts. The nut driver and extensions are mechanically locked. The change is initiated by pressing the activation button.

The entire contents of the set are neatly and clearly stored in a foam insert in which markings help find the suitable nut driver.The non-slip surface finish ensures a strong grip, even in oily or wet work situations.
