So you are also saying as a former mechanical engineer there are no applications were tighter nuts are needed?

Well personally I know a few scenarios were the nut has keep steady when its hard to do. But for that case I prefer two nuts stacked on top of each other.

They're called jam nuts and they're a nightmare in production. These days I think they're only used where the application isn't critical, the labor is skilled and underpaid, and you're fresh out of lock washers and nylocks.

I haven't seen jam nuts used outside of construction in a long time.
