Ko-ken 1/2″ Sq. Drive Impact Attack-Driver Set, 25-Pc

What it does

Converts a hammer strike into up-to-400 N·m of twist to break loose seized or rusted screws and small bolts. Hit the driver’s end with a hammer; the internal cam delivers instant, reverse torque while the rubber grip soaks up the shock.
