I bought a used OMP seat a little while ago, and I have no clue what bolts thread into the sides. Before I drag it to the store to try bolts...does anyone know what size these are?

M8-30

I use socket button heads from SPS, Holochrome.

send me and e-mail I can send you four each for each seat.

Thanks for the offer. As it turns out, the shop here carries metric stuff, in only one thread pitch, but it happens to be the right one. Thanks to knowing the right length to use it went in with only one trip to the store. 8mmx1.25x30, grade 8.8 or better is the right bolt for future reference.
