Nope I appreciate that. I know the intent was good you've helped me out on more than 1 or 10 occassions. I was just frustrated as turned into a bit of stuff I hit a lot in forums saying it cant be done. I didnt mentioned the 3/8 | 1/4" aluminium as backing as it wasnt the reason for my thread .... I had done the research and was comfortable with it. I think there are way to many geometries going on that none of us really know - the idea it will pull out even based on data I looked out is a best guess effort. Like I said Im 200% more concerned the sheet metal will tear/shear than the threads of either of setups

But anyway - moving on - we determined that 7/16 doesnt exist for a rivnut
And I do feel better having the steel (about same 3/8 or 1/4) and nut now behind the pillar .... except for that 1mm thick sheetmetal
