Where can I get coupler screws for n scale couplers
better still where can you get wheels for the replacement trucks Bachmann sell - as you will be replacing older ''Pizza'' cutter wheel's and Rapido couplers ???
You can probably get them from whoever made the couplers.🤔
Will these work?
This company seems to have them all.

If you're using MT couplers, (USA Manufacture) the screws are 00-90.
If you're using any other couplers (Asian Manufacturer) they are going to be Metric.
Most of these are MT clones.
Measure diameter and thread pitch (not TPI), two very different things.
They both can be sourced from hundreds of places.
You can also drill and tap to what you already have on hand.
Google is your friend.
Good luck
Don't buy hobby packs of screws.

Aren't Kadee couplers made in the USA?
