Funny that this thread should pop up again. I made a related discovery yesterday. I had decided that instead of carrying a tool kit with every tool under the sun, I'd go over my bikes and find what tools I actually needed. On the Bike Friday NWT I found that the hinge bolts for the seat post and the rear wheel use 3/8 inch bolts. I discovered it the way the OP discovered his 3/8; 9mm socket was too small and 10mm was too large.
It's not a big deal, but I do find it a bit annoying.
Looks like I do need to carry the American Fred tool.
