6-piece screwdriver set with Kraftform handle for pleasant, ergonomic working that prevents blisters and calluses. TORX® BO screws have a protruding pin in their drive profile. This prevents any unauthorised loosening since the "normal" hex tools cannot move these screws. Only special TORX® BO tools have a bore hole which can slip over the pin. The Wera Black Point tip and a complex hardening process ensure a long service life of the tip, enhanced corrosion protection and an exact fit. The hexagonal anti-roll feature prevents any bothersome rolling away at the workplace. Handle markings for simplified finding and sorting of the tool. Includes a practical rack for tidy storage of the screwdrivers
