The head on the Bosch Driven Nutsetter is precision designed and machined for a better-integrated fit for nuts, bolts and self-tapping screws. It is designed with recessed corners on the flats, helping to minimize the buildup of metal shavings and reduce rounding of the hex head. The Driven bit has a torsion design built to last, with a new tapered design that absorbs torque peaks to reduce stress at the bit's tip. This allows it to handle a new generation of higher torque impact drivers. The tip on this bit is precision designed and CNC milled for a better-integrated fit. The bit features clear head-type markings (or laser markings) that are easy to read and won't rub off with repeated use, as well as the distinctive Bosch silver sleeve. The strong magnetic tip helps hold the screws on the bit.
