Conversion burner exhaust pipe has 3/8 inch hole.

Gas Conversion burner 6 inch galvanized exhaust pipe has almost 3/8 inch hole poked in it for 40 years.
We're not dead yet. What is the best way to easily fix this?
3/8 inch bolt won't fit but 1/4 inch bolt is loose. I could use that and some metal epoxy.
Unless this is supposed to be there for some type of temperature probe - I'm making this up.

Do you by chance have a double swing barometric damper on this unit? Or how about a picture of the vent pipe?

May I make a guess? Somebody used it for a probe for combustion calibration and didn't close it up...
