02 housing bolts and stud sizes?

One of my studs came out recently and created an exhaust leak where the turbo meets the o2 housing. Could i just replace it with a bolt or should i throw another stud in it?

What is the size of the stud/nut?

What is the size of the bolt i should use?

Don't throw any old bolt in there. It has to be a proper exhaust bolt (regular bolts can't handle the heat cycling and degrade at a drastic rate compared to bolts/studs designed to live in exhaust systems). You can apply some exhaust paste (like for O2 sensors) to help with any future removal without seizing.

Yeah ill make sure of that. Ill probably go to fastenal to see what they have. If i have no luck there im going to order new ones online. Zinc plated bolts will probably rust real fast. Im not to sure about galvonized bolts but ill probably look for black bolts made especially for exhaust.
