2006 Trailer Hitch bolts

[x10]

I just got a hitch painted to match the red 2006 Vibe so I will be putting the hitch on soon, I'm going to pull a back hoe and a bull dozer with the vibe. The hitch didn't come with bolt to go to the frame, I know to get hard bolts grade 8 at least but anyone know what size bolts?
