I understand the main thing to know about mounting torroids and that is to not let both sides of the steel bolt come in contact. As that will create a short circuit winding that will fry the transformer.... My chassis space is limited but if I can mount a 3 inch torroid on top of a 5 inch one I'll have room. I'd be leery to pass an 8mm steel bolt through each torroid, thus coupling them on the axis. But what if that bolt were made of nylon? I seem to remember seeing commercial products that mounted two torroids coaxially, but can't find that photo now.
Do think I'm ok using a nylon bolt, I already verified on the breadboard that I can stack them with no ill effects when experimenting. So would you see any long term effects using a nylon bolt and stacking them in the permanent chassis?

I'd use a nonmagnetic (austenitic) stainless steel bolt for stacking them.
You may be able to get by with a large nylon bolt, if the finished amp
will be handled carefully. Nylon hardware could eventually loosen with
thermal cycling.

That would be better, I'll have to see what McMaster Carr has in 8mm threaded rod or bolts that are non magnetic. Thanks. Yeah they aluminum, brass and bronze threaded rods, one rod will be good for a few projects. I'll use the rubber gasket between them, and they are shielded.

There's very little coupling along the toroidal axis, I wouldn't worry about it, just don't create a shorted turn. These are power supply transformers?
