I have a board that takes a toroid laying down flat and a plastic disc with a hole in the centre and a steel bolt holds it down on the board. To assemble it a nut is manually held in place under the board while the bolt is screwed up. I was thinking how well would it work to put a steel bolt though the board with the brass nut underneath (no toroid fitted) and hope that the wave solders the brass nut but doesn’t stick to the steel bolt. Would this work reliably? The toroid is mounted after the wave soldering step.
