Read a thread on an alarm tech forum a while back where a guy in Arizona did the same thing after fighting loose screws for years. He said the heat cycling in attics is what kills you, metal expands and contracts and the screws just walk themselves out over time. Crimps don't have that problem since it's one solid connection. Idk if it's the crimp itself or just the fact that you're not relying on a screw staying tight for a decade, but either way the callback math works out.

Switching from cheap to good supplies fixes everything, same as my dull knives.

Did you ask your roommate before turning the kitchen into a bug farm?
