I used the knurled nuts to level one of the Nitto front racks that bolt to cantilever bosses. With the bottom attachment points set by the position of the cantilever brazeons, the only way to level the rack is by varying how far into the CP brake hole you insert the threaded "bolt" on the rack. Turned out the rack needed to be spaced out a few mm from the front of the fork. A few knurled nuts did the trick perfectly.

I also find these useful when mounting tubulars. When first mounting on a rim to stretch, I secure the valve stem with the nut first, to prevent the tubular sliding around too much as I stretch it onto the rim. This helps prevent damaging the valve stem while mounting. When mounting a prestretched tubular, I secure the valve stem with the nut to be sure the valve stem stays straight and perpenticular to the rim during mounting and inflation. Once the tire is mounted and inflated, you really don't need the dork nut any more.
