Are Goldstar grommets differently sized than other grommets? I'm completely baffled by what I'm finding. I have a bunch of size 00 (3/16") grommets from two different sellers; the measurements are:
Eyelet: 3/16" (4.75mm)
Outside Width: 7/16" (11mm)
(like these grommets from The Buckle Guy)
I recently decided to buy a goldstar press and the 3/16" die setter in order to stop hammering. None of my 00 grommets fit inside their press, and according to their website a 00 grommet has an outer diameter of 9mm. Are they making nonstandard grommet sizing? I really can't figure out what's going on.
