Product photo shows a circle/groove between the outer edge and hex area - is that accurate? (Need for a restoration project)

The 5 I have, have the groove. This is a small groove perhaps 0.015" deep.

Are these plugs lead free?

I don't think this answers the question. Brass has lead. There are 3 types of brass - has lead, lead free (actually a little bit of lead) and no lead certified. So are these suitable for drinking water under the new No Lead regulation?

Will this fit Will this fit air compressor in tank check valve, with 1/8 female npt threads on the side for un-loader port?

These plugs are 1/8"MNPT so they will fit into your 1/8"FNPT hole, and plug it.
