Diagonal spline?
It ought to be a thread if you've got the freewheel off, and the new cog just screws on. If it was a cassette ie a whole bunch of cogs, then they'll be on a straight spline - parallel to the axel, as it were.
Can you put a photo up? It's kind of hard to visualise...

A photo would help. But if it's old and French with a diagonal spline, I wonder if it's a Maillard Helicomatic. Sheldon seems not to have been a fan:
