What size is fh2 axle?

I just epically modded my fh2, reshape, satin, sili recess. Then the axle got stripped.  So i was wondering what size axle it uses according to: http://www.yoyoguy.com/PN/DUP11/Duncan-Parts/Short-Duncan-threaded-replacement-bolt

I measured it and it doesn’t match and of those.

Thanks for the help!

If that size axle is not in-stock there, where can I buy one.
