Those petcock screws are the rarest of the rare. Usually they are wasted when found on old tanks.

What you can do is get a M5 tap and matching new screws. Carefully chase the threads in the tank with the tap (use oil on the tap).

Then use your new screws.
BTW, I looked in my many part drawers. I don't have even one..
