This is the tool for McGard Spline Drive lugs.
NOTE: McGard recommends against using an impact gun with this spline drive tool. On our own cars with the McGard spline drive lug nuts, we do use a gun just to spin the nuts on and off faster than by hand, but we always do the final tightening of the lugs and the initial breaking loose of the lug nuts BY HAND.
