where can I look up the naming scheme for that screw size you’r etalking about?

is that the same as the phillips PH000?

is that describing the thread dimensions or the head of the screw, or both?

I’ve looked up the screw dimensions / where I can get spares but can’t seem to find consistent results for this one,

I want to know the screw’s head and thread measurements so I can recreate a custom oculus shell in CAD and have the proper screws and parts all fit back together properly.
