What screw size are the internal screws on the Wyze webcam 3

It looks like a 2mm diameter screw 5mm in length but what is the thread pitch? Is it ISO (metric) or US. And any ideas where you can purchase replacements?
I have replaced the lens with a 25mm focal length lens and want to back off the back board by 5mm so that the lens fits flush with the outside of the casing - so ideally I need a 10mm length screw or maybe a standoff pillar.
