The GripEdge Tools 45-pc Master RPT Star Driver Set, No. MST45S, includes sizes from T6 to T100, T8H to T55H, and E4 to E24. The set features Rounding Prevention Technology that the company says provides up to 50 percent more torque on new fasteners and up to 400 percent more torque on damaged fasteners. The drivers use a patented bidirectional design that enables loosening and tightening of damaged fasteners. Each E-star socket is made of CrMo steel, and the precision-machined S2 steel star bit sockets are corrosion-resistant. The entire set comes in a hard case with a removable foam insert.
