Help on name of this rivet??

[regius]

I would hope someone could tell me the type of this type of small rivet that's seen on the belt loops of this jacket. Note the two small silver rings that secures the top of the two front loops? i'd love to know what they are thank you so much!

I find them hard to see but I suggest they are 'sail eyelets'

Agreed, grommets

Thanks for the warm and prompt help gentlemen. The users of these types of "rivet" all call them as "rivet", i'm pasting another shot of the use of such "rivet" here, on the anchor of a certain vintage repro zipper, In the high end reproduction leather jacket business this is very common and desired. 

As a matter of fact, I once received a spare set from Aero Leather of Scotland, for a RAF sheepskin jacket I bought from them which has the front zipper fastened with such a rivet. I'll have to find it, it is in fact a "rivet", has a skinny pole.

I just realized Waldes Japan, a dedicated zipper and hardware reproduction maker, sells some Deadstock clothing hardwares and they have it. It’s just two parts, a flat ring/washer thing, and a rivet. No cap part. So I’m really curious how to install. Here’s the photo. The wire hooks are just what the rivets hold in place, the key is the ring and the rivet.
