I assume they have no set?

No set, but ground with a slight taper - thickest at the cutting
edge. Four or more different thicknesses.

I don't see them in the latest Starrett catalog, so it looks as though
they may have been discontinued.

Let's hope nobody in the world ever makes another slotted screw.
I hate 'em and still have my boyhood scars to prove it.
Robertson and torx are my faves, followed by hex, pozi, and phillips.
