Holding a nut in place inside tubing - GIF

And, at least in my region of the country, there was Handy Dan and Builder's Square. I often ask the Lowes and Home Depot sales quads if they remember those guys when, for a simple example, I find a pipe/tube of a desired size and its matching plug/cap... but they don't carry the matching elbow or connector for that sized pipe "because we don't sell enough of them". That's when I empty my entire cart and go somehwere else (and often this is just back home to re-think an entire project!).

When I lived in Augusta GA there was a Builder's Square there. It was renamed but I forgot what it became. It's gone now.
