Re: 4" Wooden Mecanum Wheel
They make products for this situation!

Undersized Machine Screw Hex Nuts are made slightly smaller than regular hex nuts:

Using the 10-24 undersized nut will reduce the corner to corner diameter by ~0.1 in.

If that's not enough you can use Allen nuts which would reduce the corner to corner diameter by ~0.12. However they are pricey ($0.90/nut).
