Quoted TextWhile these look perfectly well formed, the fact that you can get about 150 Grandt Line or Tichy Trains rivets, in styrene, for $2.50-$3.50 makes resin rivets a bit expensive for larger projects.
That these are resin also means that you _must_ use either CA or epoxy to secure them to all models, whereas the styrene Grandt or Tichy rivets can be attached to styrene kits or scratchbuilt components with your favourite liquid cement. Frankly that's more than enough reason to not use resin rivets or bolts without the monetary inducement.
If you like resin rivets, I'm sure these are a fine product, but there are other rivets out there that have significantly more utility and are cheaper to boot.
Many of the Grandt-line bolts and rivets I bought years ago had the heads off-centered from the shaft but maybe they have improved since then .....
It's a riveting topic though ....
Grand Line has rivets in three sizes:
0.032, 0.043 & 0.063 inches (that's 0.81, 1.09 and 1.6 mm for you fans of the metric system out there)
Plus Models have sizes 0.5, 0.6, 0,7, 0.8, 0.9, 1.0, 1.2 and 1.4 mm.
Tichy Trains have the inch-sizes: 0.020, 0.025, 0.030, 0.035, 0.04, 0.05, 0.06, 0.07 and 0.08 (multiply with 25.4 to get the mm sizes)
Depending on the size you need you may need to choose the approriate manufacturer ...
Masterclub has spherical, spherical flat, flat and two types of conical rivets ranging in size from 0.4 to 1.8 mm in 0.1 mm increments. Depending on size, you get 100-200+ for a paltry $2.35 per pack. That's a whole lotta rivets, man.
Oh, they're resin, btw.
