Just a heads up that my Tough E-Mount arrived today. First thing I did was check the thickness tolerance. It read about 2.86mm\'s give or take a fraction depending on how much pressure I put on the digital caliper (so it ranged from say 2.84 to 2.87 or so at various points around the mount). The variability was probably not as much due to any issue with the mount but with how I used the Caliper. I\'m sure there are much better ways to measure more accurately and consistently using better tools. Nevertheless, I felt reasonably comfortable with the tolerance.
To make sure I did not drop any screws onto the sensor, I ended up using an old lens cap turned upside down, which I was then able to easily slide around with one hand while removing the mount screws with the other. The top metal mount plate came off easily (I held the lens release spring down while doing this) but the plastic flange underneath was stuck down a bit and required a little effort to remove. The new Tough E Mount screwed in easily without issue. I always like to turn the screws back a tiny bit just until they drop in as a precaution to avoid stripping btw (I\'m sure most of you guys do this). Of course I also tightened them down bit by bit cross directionally from one another.
I then measured the thickness of the old Sony metal/ plastic sandwich mount. It seemed to actually show a bit more variability in flatness than the replacement mount (2.84 - 2.9). I do believe the new mount might be a fraction thinner than the original mount as installed, perhaps due to the greater variability in flatness with the plastic piece? I don\'t know (or maybe I just tightened the new one down more). I say this as one of my alt lenses + adapter would just previously barely hit infinity and now it goes ever so slightly past infinity.
Finally, I mounted a number of lenses+adapters on the new mount. At first I was very worried as the first lens I tried would not turn and click into place. I applied a little force and it finally mounted. The second time I mounted the same lens, it went on smoother. A had a similar experience with a few other lenses/ adapters. Some fit snug with no play at all, some have a tiny bit of rotational play. I\'m fairly certain that\'s just due to the different adapters in use. It does appear though that the Tough E-Mount metal mount flange that holds a lens in place may need to be exercised or \"broken-in\" a bit.
Anyway, if I notice any issues in use, I will certainly let you guys know.

It does appear though that the mount springs that are part of the flange that holds a lens in place may need to be exercised or \"broken-in\" a bit on the Tough E-Mount at first.
