What does that solve? Isn’t the whole purpose of a threadlocker to keep the screw in place? I can imagine that plastics are soft enough that they keep the screws in place on their own. As far as I know, and from my own experience, there’s been no trouble with screws loosening over time in those consoles, so I don’t know how adding threadlocker would help.
That’s pretty cool. I wish more devices had brass inserts. I kinda hate the idea of screwing into plastic. Anyway, do whatever you feel you need. I don’t think it’d get loose even with daily usage, but I might be wrong.
