No problem Michael. I'd love to figure out how I can reinstall the rack with some confidence that it isn't going to come crashing down.

Where can I find out specs on these structural screws. How fine pitch are they and how thin of metal can I install them in.

If they are 20TPI for example, and I have .060" wall steel wall joists I don't even get 1-1/4 threads.
