Nutsetters

Nut setters are bits designed to drive hex head nuts, screws, and bolts by machine tools such as drills and impact drivers. Rather than using a manual tool, nut setters let operators install or remove many fasteners quickly, especially where many repetitions or tight access are involved. They typically have a recessed end that fits over the nut or bolt-head and often feature magnetic or locking retention to hold the fastener securely.
