Ext mani stud same as O2 Housing?

[JwpRider]

I am gathering all items to install new a new turbo and noticed I did not pickup a new stud to mount the O2 housing to the turbo hotside. (I did get the new bolts). I was searching through my other new, OEM parts and found an exhaust manifold stud (the larger one), which fit nicely into the hotside, and seemed to be the correct length. Just wanted to check if these two studs share the same partnumber or if there a difference in materials. Looks like it will be fine, but just want to check...
Thanks for the help!
