In the meantime, we made some improvements to the manufacturing process so the screws now have a slightly looser fit and are even better aligned for easier opening and closing. This should mitigate some of the problems.
Despite having a minor issue with the deformation of its screws, I'm quite impressed with the results, but I think the original design would've been slightly better
[not sure if I missed something or not but in theory, slightly looser fit screws provide a bit more room and that could lead to a higher degree of deformation].
I oversimplified a bit when talking about a screw fit. We didn't make the holes larger or made the screws looser actually. The main difference is that sockets now are better aligned with threaded holes, so screws are easier to put in. In the past we had a bit of difficulty during manufacturing where sockets and threads (they are on different plates) were not that perfectly aligned as well as their angle was sometimes not perfect. I am talking about some minor things, that come from the fact that machining stainless steel is pretty hard, even using proper machines and tools. We just improved the process a bit.
So the previous situation was that it was sometimes a little bit hard to screw the bolts in (even at room temp). Now it is much smoother like it should be. However, the dimensional tolerances of the screws and threads are still the same and according to proper norms. The screws and threads offer the same durability, it even might be better now as it's easier for the user to completely tighten the bolts. Hope I cleared things up.
