Frequently Asked Questions

What is a magnetic nutsetter?

A nutsetter is a socket style bit for driving hex head nuts and screws, and a magnetic version holds the fastener on the bit with a magnet. That makes it easy to start a screw one handed and keeps it on the bit while you position it. Nutsetters are widely used in roofing to drive hex head screws.

Why choose the 65mm length?

The 65mm length is a compact all round size that is easy to control in a drill or impact driver. It suits general driving work where the screw is easy to reach, and it fits into tight spots without a long bit getting in the way. For recessed work, a 150mm nutsetter gives extra reach.

Is this bit for an impact driver?

Yes. The 1/4 inch hex shank with a power groove is made for impact drivers and quick change adapters. The Supabit Extreme Impact range is developed for the high torque output of an impact driver, and the torsion and hardening are built for that kind of work.

What is the 3X torque claim?

The listing states the bit is torque tested to exceed DIN standards by up to 330%, which the range describes as 3X torque. That means the bit is designed to handle high torque impact applications without snapping. The cold forged S2 steel and manganese phosphate finish support that strength.
