These Pozidriv screwdrivers are from the Ergo range by Bahco. Exhaustive studies and tests – both practical and in the laboratory – lie behind the handle design of Ergo screwdrivers. This has resulted in a handle that has different diametrics for different functions. The large part of the handle allows high torque to be applied, while the small part of the handle can be used with a lighter touch for speedy tightening or loosening of screws. The blade is made of special hardened steel, plated to stop corrosion, and the tip is of Propoint design – phosphated for maximum dimensional accuracy and no peeling – and meets ISO standard 2380.
