I use several different things. But I would say that Raaco fits for your purpose. They can easily be fixed shop, semi-mobile, mobile. The modularity makes them completely transferable and re configuring is a snap. EX- when adding in a new size of screw or what not. I have my shop screws (except for bulk extras / refills), and my mobile screws in Raaco. I can take just a couple containers or a whole rack box. They happen to work nicely in tool box drawers too.

I do use Plano for all sorts of misc. hardware and such. Cost wise if it could all be Raaco it would be. But I don't use or move the misc. to justify it.

I also have some parts sorter bins for larger misc. stuff.

Raaco makes boxes to hold smaller quantities of "compartment / containers" too. Sometimes those are good for just taking a few sizes. And there are about twice as many size compartments available as what comes with the Tanos Racktainer. Basically every modular increment in both row and column is available.
