I bought a set of five of these bolts from a nico sponcer. I don't remember which one but I'm sure you'll find it if you look around. It's the same bolt on the SR as well.

I dunno what the size or pitch is but it's extremely common. Go down to NAPA, Partsource, Autozone, whatever parts store like that you have locally and look through their nuts an bolts, they'll have it for sure. Even if you're not sure you can probably eyeball which nut you need and you'll be right.

It's also one of the most common thread pitches on S13's so if you've got spares some of them might fit too.

M8x1.25

its the same pitch as every other bolt on a 240sx. FRSport sells studs and lock nuts.
