Dumb question?
Hey believe it or not i know what your talking about ....they make a set of impacts from eastwood that are real skinny and coated with a special rubber or plastic to keep from scratching you wheels thats one place i know you can get them from
Unless you opt for really fancy lug nuts like these.
Scroll down to the Muteki's.
I'm just using these as an example.

Since the spline is doing the driving it keeps the nuts looking nicer.
As for stock lugs your out of luck if you use an impact. My .02
