O2 bolt size

Hey I just bought a tubular exhaust manifold and realized I'm going to need the O2 housing bolts to bolt it on. I just need to know what the threads are on the bolts so I can go to fastenal and pick four of them up. Thanks

They are 10mm x 1.25 thread. They have a 14mm head. I'd guess around 30mm for the thread length. Remember that one is a stud and nut too.
