I think they are Gorilla, not McGuard.

They seem to have a couple of different kinds. One of them has a free-spinning outer sleeve. The other kind has the "nut" (which looks like a spline drive) split into upper and lower halves, and I think the upper half is free spinning and the lower half is the part that you actually spin to remove the nuts.
