I doubt the gripping rings on the tail end of the pipe clamps will grip the EMT. The
gripping rings are chromed steel. The EMT is chromed or some kind of gray plating. Its
slick. I don't think the rings will grip the slick EMT pipe. So no clamping force. I don't think it
will grip enough to even dent the thinwall EMT. It'll just slip.
EMT is NOT chromed, it is electro-zinc plated.

OK. But my point is still valid. I don't think the grip rings will work on the electro zinc plated
coating. Too slippery.
They work fine on clamps that come with electrozinc plated "pipes"
from the factory.

Perhaps for some definitions of "just fine'. I haven't had good experiences using pipe
clamps with galvanized pipe.
