I would hope no one would use one of these monstrosities on a head, but none the less I found myself fighting head bolts a little while ago that must have been put on by a gorilla. The spec is 50 ft-lbs, and I couldn't get them to budge with my 6'2", 260lb self leaning on a 2-ft breaker bar. I'm recharging the cordless impact wrench(no air in my garage) to hopefully have a go at them.
All of that aside, I don't see the advantage of using an intermediate tool when I'm torquing my lugnuts. I typically spin them on with my impact gun but stop well before it "clicks". I then hand tighten in the correct sequence with a socket held in my hand(or sometimes just by spinning the nuts), torque to half the spec with a torque wrench in the correct sequence, then follow up with the correct torque. That's how I was taught to do it-in fact on engine heads(which I know are a whole different ball game) was taught to tighten in sequence the specified sequence in 5 ft-lb intervals.
BTW, one of my cars calls for 65 ft-lbs. It seems uncomfortably low, but at the same time I've never found a loose lug nut. I have to be careful with the torque wrench-it's easy to go over with that, and you have to be johnny on the spot with the clicks. I actually use a 3/8" drive torque wrench on this car just because the "click" is better defined at 65 ft-lbs than it is on a larger 1/2" drive wrench.
