Terminal screw size for Nema 5-15 plug?

According to Hubbell:
Product Datasheet -- HBL5266C

Not my area of expertise, but I would not assume all brands are the same automatically. I would assume the outer parts fit a standard, and probably the insulative qualities of the housing, but the interior can be whatever dimensions the maker cares to make them, within terminal isolation requirements. I could be wrong.

In my minds eye I'd guess 8-32, which agrees with that data sheet.

Aha! Simulpost...
