The screw on pedal C has snapped off and the stub is still in there, you can see the ones on pedal A&B with the lock nuts in place. It's very close to 4mm but I guess it's an imperial size not metric! Any help would be great.

I'm guessing here the stop screw is 10-32. 4.763mm is 3/16 Imperial which would be the standard hole drilled for a 10-32 screw to drop through. Which would mean the screw would be very close to 4mm.
Jim Palenscar here on the forum would be the person to contact.
Good luck
Barry

I just measured an early 90s Sierra Session I have in the shop and the diameter is for a #8 screw. Mine does not have any jam nut, or lock nut in place, so yours may differ. It could be an 8-32 or an 8-36. Likely 36 teeth per inch (UNF) for fine tuning.
If you can get some calipers to measure, here is an ANSI/ASTM thread chart for all classed screws.
