Good engineering

Recently, I came across an even smarter thing: The nut had an elliptical hole and canted threading and mating sufaces. You could slide it on almost all the way and only near the end the canted mating surface made the threads engage. A few turns would be enough to tighten it.

I have that sinking feeling. Midnight plumbing? Some things are best done under cover of darkness.

Extra long stamped sockets are common for shower valves and basin (sink) installations.

Now, that's nice. I haven't seen that. I usually see 2 round holes at one end. Insert included rod or round screwdriver in both holes and I have a "T" wrench. The "T" handle system is difficult to tighten properly.

I wonder what problem they're trying to solve. My guess(tm) is that everyone keeps the supplied tools and stores them in an obscure location where they cannot be found when needed. It's easier to provide a "free" tool, than to deal with an irate customer demanding to know if the tool was lost in shipping or stolen at hardware store.
