Screw Size Identification

I need to replace a small screw that I drilled out of a keyless entry fob for my vehicle (it was stripped). It is a flathead metric screw and is about the same size as a 2-56. In fact a 2-56 will just start to grab but then seize up. What is the equivalent metric size to a 2-56? I measured the diameter of the screw using my calipers and it is about 0.075" (1.9 mm) with about 55-60 threads per inch.

I used to own a mobile electronics store and had people stopping by all the time for odd screws and parts.

if you have a store like that..... give them a try. Otherwise I have no idea where you could find just one or two screws of that size.

Try the screws in a eyeglass repair kit.

Or if you have any old remote controls or cell phones laying around, might be something you can scavenge.

Turned out being an M2. Had to order 50 of them (McMaster). Only $5, so no biggie. I have 49 spares though. Kind of wasteful.
