19er nut with as little outer diameter as possible

Hallows With a certain aluminium rim there is only so little space that a normal 19er nut fits only very briefly into the holes. A already nut with plastic wrapping never fits in. The aluminium rim is now also seen that a 19er nut has hit against them often. Are there 19er nuts with very small outer diameter for such stupid aluminium rims with very small holes?
