Tiagra 80W side plate screw size?

[Puhi]

Anyone know the thread pitch and size for the Tiagra 80W side plates? Would I be able to find these at a hardware store?

A normal, common M5 or M4 maybe, i don't have one here so i don't know for sure. As for availability, i would say that any hardware store in the entire world would have one that fits. In the USA, who knows...
