Fastener-Holding Nutdriver Bits
A mechanism inside the bit holds hex nuts and cap screws in place.
Bits with magnet hold steel fasteners.
Hex shank bits (also known as insert bits) are used in hand drivers or with a bit adapter in power tools.
Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.

Extra-Grip Fastener-Holding Nutdriver Bits
Because they make contact on the flat sides of fasteners rather than only on the corners, these bits significantly reduce slipping and stripping. The groove in the shank fits directly into power tools. They are also known as lobular bits.
