DZUS fasteners alternatives?

[Erich]

We lazily call them all T nuts here, though Nutserts or other names crossover. I set some open stairway treads with the stainless threaded ones, in order not to see or have to plug a screw from the top. I have also used things called Rivnuts in cars.Much like a pop rivet, but with a threaded interior. Takes a special tool to set. There are also nut plates which I have used on my Rep, in order not to have to weld nuts on the body.
