Frequently Asked Questions

Why are nutsetters used in roofing?

Hex head screws are the standard fastener for metal roofing sheets and flashings, and a nutsetter is the bit that drives them. A magnetic nutsetter holds the screw on the bit so a roofer can start it one handed. The sizes in this set cover the common hex head screw sizes used on metal roofs.

What does the torsion neck do?

The elongated torsion neck twists slightly under high torque instead of snapping, which gives the bit a longer working life in impact applications. It is a feature of the Supabit range designed for the high torque output of an impact driver. The result is fewer broken bits on the job.

What sizes are included?

The set includes three 65mm nutsetters in 1/4, 5/16 and 3/8 inch hex sizes. That covers the common hex head screw sizes in roofing and metal work. Match the nutsetter to the screw head size so the bit gets a full grip without rounding the head.

Do these fit my impact driver?

Yes. Each bit has a 1/4 inch hex shank that fits impact drivers and quick-change adaptors. The bits are built for high torque impact use, and the magnetic tip holds the screw on the bit under vibration. Keep the set together so the right size is always to hand.
