High quality Micro screwdriver set for precision fittings. For TORX safety fittings: TORX® BO screws have a protruding pin in the drive profile. This prevents unauthorised loosening, since these screws cannot be used with standard TORX® tools. Only special TORX® BO tools have a hole that matches the pin. The screwdriver can be turned extremely quickly by supporting the hand on the pivoting top, thanks to the fast rotation zone under the top. No time-consuming repeated movements are required. Impact zone with integrated soft areas guarantees the transmission of high loosening and tightening torques. Precision zone for correct angle of rotation while performing adjustments. Black Point tips provide the perfect fit and optimised corrosion protection.
