This easy carry 36-piece set of Torx® Bits and Sockets caters most Torx® jobs for experts and DIYers with impeccable fastening experience. The bits are made of high-grade S2 steel (carbon, silicon, manganese, chromium, molybdenum and vanadium) while Chrome Vanadium drive sockets provide excellent rigidity for strength and top resistance to corrosion. Sizes ranging from T8 to T60 (Torx® Bits) and T8H to T55H (Security Torx® Bits), and a series of External Torx® Sockets make this set handier than ever. And of course, a T47 is included for working on some GM and Japanese vehicle models.
