You mean on your feeder? The screw just left of this arrow head?

I don't know the answer but everything Ultimaker seems to be metric so probably 3mm or maybe 2.5 or 2mm. Probably 3mm.

    It is indeed an M3 x 3mm, I ordered some from Ali in China some time ago for spares, make sure you order ones with a flat end not a point. The first ones I ordered had a tapered point and they do not work that well so I had to file the end to get better grip on the rod from the stepper motor.

    The smallest of the three hex keys supplied with the UM2 fits, 1.5mm I think
