I have to many projects on the bench and need to try a complete unit. I have the RF amp, detector and AF amp looking good so what I need is a tuner. I'm using the 1920's crystal set as my basic circuit. What I'm looking at is like this.
Pop rivets will work too. The hole in the center and a method of attaching the wires is the draw back with them.
The founder of The Radio Board (Mr Dave) used these with good results. Fixture screws hold the globe on ceiling fan light fixtures.
I plan to use fixture screws but for the proof of concept will use screws. I have the prototype assembled except the armature.It will need a knob. I have the glue drying on the knob and will finish it tomorrow.
