Truss Rod adjustment just turns forever.  Is it supposed to be a 4mm hex?

The guitar is a good-looking DK20T and it's just too nice to part out.

Any help?

The SAE standard size truss rod nuts are 1/4" 5/16" and 9/32".  Metric sizes are 4mm or 5mm.  You should be able to "feel" if the wrench is not making solid contact and is just spinning away, or if the rod itself is just turning.  If the rod itself is spinning that's a pretty major fix.
