The tailpiece and bridge are made by TonePros. Metric of course since they’re on an Epiphone. Id have to double check. But pretty sure the bridge has the set screws as well. Makes it so you don’t have to hold in place while restringing. Or while the strings are off and you’re cleaning, they don’t fall off. Not a huge deal, but I sorta like them. Best part was. I was having tuning and intonation issues with the Epi bridge in place. Put these on and my problems went away.
The TonePros is much better than the Epiphone bridges but not a big improvement on the Gibson, just the grub screws keeping stuff on, as you said. They don’t lock rigid. For a true locking bridge look at the Gotoh 510
