The 76421 EAB Torsion Impact Rated Torx Bit (T15 x 3") is designed for high-torque fastening and the kind of impact-driver work that quickly separates strong bits from disposable ones. Built from specially tempered S2 spring steel, this industrial-quality bit is engineered to flex slightly under load, helping it withstand repeated impacts without snapping. The reduced, rounded torsion shank improves balance and reduces vibration during use, while the milled, non-coated hex shank ensures a precise fit in modern impact drivers. Each bit is magnetized to securely hold fasteners, and the color-coded design allows quick identification—because no one enjoys sorting through a pile of identical-looking bits while a job waits.
