You mean they spin enough to drag the nut with them and unscrew it? I guess the ones on the right side could do that; there's a margin of functionality - I think your problem is that you overtightened the nut, so it was getting too much friction from the spinning of the wheel, but if you loosen it too much, centrifugal force could induce the same effect.

Just got to stay within that margin there.
