The metric one I bought...

has the size permanently engraved into each piece as can be seen by mousing over the last product photo on that page.

Given the fact that the piece is held in the fingers and rotated in use, almost any write-on label is likely to wear. Sharpie now sells oil-based paint markers in medium point...

and extra-fine point...

Once dry they might resist wear a bit better.

I haven't tried them yet but intend to order some of both on my next Amazon order. I love their metallic color (gold, silver, bronze) markers for marking dark-colored or black objects. The markings really stand out.

I have to agree on Starrett's pernicious use of proprietary threads. I ran into that while restoring the fine adjustment screw on a height gage I inherited. Strange practice considering that the bulk of their customers probably have access to a screw-cutting lathe and know how to use it.
