Phillips pan head.
Thread looks like it could be a sheet metal screw.
Beyond that would require at least need a Sense of scale.
Diameter & thread pitch/threads per inch wild really help.

Structural
Buy a stock plastic or aluminum thread gauge and see which pattern fits the threads on the screws you have in hand. Buy both a metric and an imperial gauge to be sure to accurately size them up.

Those could be PT screws:
If they are not PT thread form, then the question about metric and inch is moot. The standard sizes for tapping screws like these are 2.9 mm, 3.5 mm, 4.2 mm, etc. These correspond with inch sizes 4, 6 , 8, etc.
