Default size/pitch of tail light flange nuts?

I'm laid up in bed recovering from surgery, and I can't scratch this one itch that's been driving me nuts so to speak...

Does anyone know the size & pitch of the tail light assy/ rear trim panel flange nuts? PN# 99940-0503. Much to my surprise, they're smaller than M6x1.

Thanks for humoring me!

It's going to be M6x1.0 or M8x1.25.

M6. However, the tail light nuts are M5 with 10mm heads.

Ah! OK. I remember trying to put a M6x1 on it, and its definitely smaller. So... M5 fine thread is typically .8 pitch, right?
