Inside rear view mirror screw size

[Kringle]

Hi all. I sprung for a new inside rear view mirror for the 40 from Toyota. It didn't come with screws. I have no way to easily size them. Does anyone know off hand what the screw size is supposed to be for the pre-threaded insert holes in the windshield frame? 2 screws required.

Thanks.

Maybe this will help.

Hi, thanks for this. I thought it might be an M5. Definitely not that screw though. It has to be a flat head to fit into the countersunk hole in the bracket and not stick up past flush so you can snap the mirror on over the top. A round head screw will stick out too far.

They look like these. Just not sure of the exact size.
