Exhaust flange Studs/Bolts

[solis]

hey guys i need to know what size are the Exhaust flange Studs/Bolts? that attach the x pipe to exhaust manifold.
I accidentally rounded one nut when i installed the x pipe. Also is there an easy way to remove the nuts? i think i need an 18mm mid length socket to clear the k member, is that right?

That’s right for the socket size

That’s right for the socket size

thanks i had a felling that was the size after i rounded the nut with a 19mm. I still need the sizes for the nuts and studs hopefully someone can chip in with them thanks.

Usually the nut is a "jam nut" and is prone to destroying the treads on the stud. Do yourself a favor and get stainless hardware if you can.
