bolts of any importance need to be torqued down, I imagine you could adjust the torque setting on the drill, but I don't think the setting numbers have any particular calibration. An impact driver is more usual. Unless going into a casting or something, you need a spanner on the other end.
I drive hex-headed coach screws with mine, usually M6, for heavy outdoor work. It does tend to run the batteries down.
I have sockets that fit the drill attachment. Mine are 1/4" drive. They often come in kits with screwdriver bits. Wear is heavy so better ones are made in a hard steel alloy. I can't remember what it's called.
edit: Chrome molybdenum alloy steel They are usually grey/black, not chromed.

you can get cheaper Chrome Vanadium ones for use with a hand tool, throw them away when they show any sign of wear. Don't use plain carbon steel, it is not strong enough.
