It's metric, trust me.
Not only is the axle metric, 12mm, there are 4 different thread pitches it could be, 1, 1.25, 1.5, 1.75. I'm in the middle of a storm right at the moment, if no one steps up, I'll measure the nut tomorrow afternoon. |

I believe my Gio quads are 12mm 1.5 thread pitch. You can buy a thread pitch gauge to check if nobody here knows. |

M12 X 1.25 (which is kind of an odd-ball thread)
Actually, a Dodge Mini-van uses this thread pitch on their wheel nuts, if "stuck" you could reverse, and use one (it would look goofy as all get out, but it should work). |

I think a 1.5 would be worse, but still an odd one to find.
Is it a castle nut too? I'd have no idea where to find something like that. |

Locally, I would check a nut and bolt supply, maybe a garage that specializes in front end work, and if a locking type nut was not available, i would drill the end of the axle for a cotter pin.
For your reading pleasure: http://en.wikipedia.org/wiki/ISO_metric_screw_thread Actually, in North America, the "usual" fine pitch for a 12mm bolt is 1.5, though most 12mm fasteners use the coarse pitch of 1.75 (meaning: you would be hard pressed to buy a tap, and die, set with this size in it). Changing the axle bolt with a "regular" 12mm bolt is a no-go because the shoulder on the bolt is sized to fit the front wheel bearings, though another axle bolt would do. |
