Wing nut driver!

They have them. This one kind of defeats the purpose of using a wing nut if you are going to drive it on with power tools....

Actually, this one is listed as "Wing nut and Ceiling hook lag driver." Ceiling hook lag driver sounds a bit more reasonable than a wing nut driver.

Well given it fits in the handle I would guess it's the slot part that is meant to do something. But I'm damned if I can think of anything that is that shape.

Well done, mrodgers.
Now my mind is clear again and I can think about something else then this thread and tool.

Hopefully you'll get some sleep tonight

Whahha, thats a good one

Ontopic, i think that its a extra part for screwdriver itself so its more comfortable to screw things
