@Jayro I did get the correct screws for the box. And boy, now I know what you mean about "the satisfactory click". The box works PERFECT! Thanks a lot mate. My aunt is amazed
I probably went through 6 or 7 latch revisions until I got the feel.and tension of that latch click "just right". It be either too soft and risk popping open, or too hard, and I'd have to pry them open with something like a flathead screwdriver. But I eventually got them dialed in perfectly.
