BioniQ screwdrivers with a hex 1.25 can be used for almost all screws of the BioniQ system. Only the universal Uni-Base AN bases and AN screws require the use of the special BioniQ AN/tx1.9 screwdriver with hexalobular shape. Only the use of original BioniQ screwdrivers will ensure that the screw head will not be damaged. A visually identical screwdriver may have a different head shape in detail. Its use can damage the screw head even when the recommended tightening torque and angle are followed. Future loosening of the screw may be difficult or impossible.
