Screw size for the Apple Pro Speakers? (clear orbs)

[Yr Blues]

I somehow lost all the screws for the front rim of these. They work fine until higher volumes and then they pop out of the enclosure and the audio turns to crap. I need replacement screws and I don't know what size. Very shallow, like 1/8th inch.

Looking at a picture of the screw, these look like smaller versions of the screws that hold a 3.5" HD in place.
HD screws are UNC (Unified National Coarse) #6 (32 turns per inch) , so at a guess the speaker screw is a UNC #2 - 56tpi, which would have a diameter of 2.184 mm.
If the hole is bigger (2.515 mm) it would be a #3, or smaller a #1 (1.854 mm).
#4 is 2.845 mm.
The screwdriver head is Philips.

Thanks. I'll try to get a set of those. Or in a set like these.

@Yr Blues Not M2/M2.5/M3, as the picture shows a much coarser three pitch than the Metric range.

So the first set, maybe? Not sure about the countersunk angle on those heads or if they need to be flat.
