Typically M3 or M4. Any machine screw from Screwfix or B&Q should fit.

they're not always the same, but rear derailleur limit screws sometimes fit. if you've got any broken rear derailleurs kicking about...

You probably can’t PM yet but if you can drop me your address and I’ll send you one, got a box of scrap bits and pieces that has some.
