Terminals spade type loosening the binding posts

I'd like very much your suggestion.
The use of spring washer can be probably a very nice solution.

Thanks a lot

Is there a reason you don't terminate using locking banana plugs?
Have you heard of Blue Jeans cable
ultrasonically-welded terminations include locking banana plugs

The reason I prefer to use spades instead of banana plug is that the banana terminals stay in a position ease to be accidentally removed by a “ blind “ foot!
