Inspector cited this?

Ok, this one would be cheaper to make, with the cap being available off-the-shelf.

Over 100 posts, wow.

Hey! This is serious stuff.

I used to work on a machine that had a threaded insert. It was threaded on the outside and had a slot in the top to tighten it into the machine. The inside of the insert was also threaded so the cover screws went into that. The insert wasn't just for the other screw to go into, it also held something in place.
Both pieces had to be secured in the same location so "stacking" the screws (for lack of a better term) was the best way to accomplish this.

Looked eerily similar to Peter's drawing!

many stackable switch blocks are similar in design.

Peter's second drawing is something I have seen before as well - just not for the application in this thread.

Indeed. A $2,500 R&D project to solve a 20 cent problem.

:lol:

Never knew my post went this long. I hadn't even been here in a while. It take some time to read all these posts.
