High quality Wera Micro screwdriver set for precision mechanical work. Suitable for TORX® BO safety screw connections: 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. Rapid twisting is possible by fixing the hand on the twist cap and using the fast-turning zone just below it. This makes time-consuming grip adjustments unnecessary. Power zone with integrated soft zones ensure the transfer of higher tightening and loosening torque. Precision zone for the right angle for adjustment work. The Wera Black Point tip offers high corrosion protection and an exact fit.
