I sometimes find 4 boards a bit limiting, I can work around by mounting 2 screws higher and 2 screws lower (hence only 2 screws holding a few of the boards) but would prefer dedicated mounting screws for larger stacks. More mounting screw choices in general would be great.
I support this. Is there a source for longer screws? I could not find anything/anyplace obvious as a source.

There are a few suggestions for threaded rod at http://forum.tiny-circuits.com/index.php?topic=221
This somehow dropped off our list of things we really need to carry, I've added it back on.
This is so called M1.2 screw, which comes with various length. You can order at
