Xt10i screw size help please

[Tot]

Does anyone happen to know the size of the small, black, flat-tipped, philips head screws that hold the primary mirror cell in place. These are the screws on the outside of the OTA at the end, just above the black "collar" of the mirror cell.

Thanks.

The ones on my 8" XT8 are M4, I would be surprised if the XT10 are different.

Thank you, Peter. Now off to find some M4 5mm screws!
