Looks to me to be GM part number: 15756879 (STUD,CTLTC CONV FLG(M10X1.5X40MM)(BUTTON HEAD).

Found it here:

Looks like you can get them from e-bay or Amazon. Seems to be about $8 on e-bay:

.

Hope that helps.

I just replace them with a bolt and nut from the hardware store it makes no difference in sealing/exhaust leaks.

And if it breaks when removing it a bolt is a lot easier to get out. More than likely it'll fall out. Also about $7 cheaper each. I usually have to heat those studs when they break and use an air chisel to drive them out even heated.

Yea, you should see what Toyota does with the o2 sensors you have to go back to studs. It's ridiculous honestly.

Chevy at least all of the ones I have owned are simple.
