Thread pitch for sidestand bolt/nut?

1986 VFR700

My sidestand nut has gone awol (I'm now blaming the Santa Cruz Mountain Metal Rats to this). Not sure why/how (I've never loosened it), but due to how the bike went down once long ago, the nut took some rash and may have been loosened up from it's proper torque.

parts fische says 10mm, but doesn't list the pitch. 1.5mm seems to be the standard threads. Or, I could just pick up flanged locknuts in all three pitches and call it good. Working a mile from a Fastenal has it's uses.

 

And with that, anyone know what "bolt, u" means in the fiche and fsm? It appears that they are one of the locking flange bolts. Probably explained in the common manual?

 

It's M10-1.25
