What are these two screws?
One of these things was found on the table below the printer the other day. It's a screw with a hexagonal hole in the other end and usually used for holding a cog in place. But I don't remember having tightened one in assembly. I thought maybe it's from my previous 3d printer, a Wanhao. Today another fell out so it must have come from my MK2S. But the printer prints just fine. Where have they fallen out of??

It is a little hard to tell the size exactly from your picture but I would check the two 16 tooth pulleys on the Y or X axes motors. They both use small screws like that to secure the gear to the drive motor.

Re: What are these two screws?
yes, these little grub screws are commonly used to assemble the pulleyes to the stepper motor shaft (x-motor, y-motor or even extruder).
but if you've previously had a wanhao, it might be that they are from the coupler for the z-motors and the trapezoid spindles as well (they use the same grub screws).
