fastener questions from a rookie

1. Is it acceptable to use tinnerman nuts and sheet metal screws to attach adel clamps to let say a subpanel?

2. Are the grasshooper nuts the way to go to attach gauges to the panel?

3. Which method is best-using panel switches with fast-on connectors or screws for ring terminals? Or, put it another way....how hard do the fast-ons separate (after years of use) for fear of yanking out the panel in the process?

Or are these tings Potato Potahto

Thanks for the feedback

Depends on how much you want it to stay on. I only use screws and self locking nuts.

They are acceptable. If you mount the instrument behind the panel get the ones with the legs, they lock into the instrument.

I prefer ring terminals and screws, but sometimes you have no choice.

Tinnerman clamp nuts with the correct screw are acceptable in certified planes. The springiness in the teeth that hold the screw provides the self-locking ability.

One easy trick is to use a #8 U-nut on one leg of an Adel clamp. To hold a wire bundle to a flange, only a #19 hole needs to be drilled, no difficult to get at plate nut needs to be riveted in, or difficult to get at self-locking nut to install. Just mount the Adel clamp against the back side of the flange.

Gil....Very Nice. That would save time, especially in cramped spaces.
