drive screws, but thin heads?

Im wondering where the heck to find some screws that will let me fit some HDs into my Lian Li V2100!

They are the normal thread, but about 2mm black and then a flat and very thin head... Seriously even way under 1mm

I have of course botched a few in using various methods, but I would really prefer to do it properly.

I have contacted LianLi, but they have failed to reply, and I have tried ebay, so I thought I might ask here?

could it be these ones?

a list of screws here, maybe have a look at them and then search the part number for UK websites

The first link = no.
I have loads of those and the head is just slightly too thick.

The second link however... There is a LianLi Series V screw that does look likely, so many many thanks on that.
