Yes, F = Fil = Thread. On an Italian crank it would stand fo
r Filetto I think. Interestingly I bought a pair of NIB Stronglight c
ranks marked with French threads that were actually 9/16 x 20. I have
also found Campagnolo pedals tight in Campagnolo cranks, both with seeming
ly good threads. I ended up buying a set of 9/16 x 20 pedal taps.

In a manner of speaking... :-)
Lyotard in particular was well known for producing pedals that could be used in either English or metric arms, regardless of how the pedals were marked.
