What makes this a "high quality" "premium" ceramic octal socket?

It appears that the lugs on the bottom of P-ST8-802 are thicker and more robust than the generic (P-ST8-801) version. Also, there appear to be spring loaded metal inserts in the pinholes for securing the tube in place. Other than that, they appear nearly identical other than the slight difference in color
I'm the asker and I don't see that "spring loaded metal insert" feature in the pin hole. Are you perhaps seeing a ghost of the rear twisted lug terminal? I do see evidence of silver tarnish so must assume silver plating is used.

When looking at the second (middle) photo, you can see two "U" shaped metal inserts on either end of each slot. These grab the pins of the tubes tightly and they are not included on the P-ST8-801.

Do you carry the mounts? Can't seem to find them here.

Electrically speaking, these are very high quality and hold tubes very tightly. The one problem is that for chassis holes that are slightly too large, it takes two of the "saddles" (mounting rings) to hold properly.
For this reason, they should be sold separately.
Very high quality replacement socket. The On / Under chassis saddle feature is unique to this socket. The saddle does not contain solder lugs, so if you need ground to chassis solder lugs buy yourself some chassis solder lugs before starting your replacement project.
Well built socket that holds the tubes (in my case upside down) good and tight. Not the largest terminals, but this shouldn't be a problem if you select the right wire. I'm going to order a few more of these.
