I was trying to get these tiny screws down to hold these wires the other day, but I didn't have the recommended 2mm screwdriver. But I really wanted it done, so I tried a 2.5mm screwdriver and something on a colleague's Leatherman. I did not get it done, and of course, stripper the screw a bit.
At home, I found a 1mm screwdriver, which is not quite the right tool, but closer, and it was easy. I really should not have bothered with the "elbow grease" and the wrong tools.
