A comprehensive Torx® system of bit sets and sockets that equips professional mechanics with impeccable fastening experience. 17 Conventional Torx® Bits ranging from T6 to T70 are complemented with same number and sizes (T6H-T70H) of Security Torx® Bits. And of course, T35, T47, T35H and T47H are included for some GM and Japanese vehicle models. Wherever high torque is needed, a series of Torx® Plus bits can precisely fit in the respective screw heads and ultimately provide zero camming out experience. Moreover, a series of External Torx® Sockets completes this set.
