M3.5 x 0.6 is also a size, as are M3 x 0.5 and M3 x 0.35. If the diameter is a full 3mm, I would guess M3.5 x 0.6 because the OD across the crests on a metric thread is always slightly smaller than the nominal OD. It could also be 1/8 x 40TPI which is a commonly used thread on pendulum rods (Model Engineer series) but that has a 55 degree Whitworth form with rounded roots and crests.
What are the measured OD and the pitch, and the flank angle?
