Riv Nut Tool - Rises from the Scrap Bin
Had to fit a few riv nuts to my kit car chassis. So dug out the old one...home made...very simple.

Then I remembered that I did not like this one very much as you were actually using the "nut's" threads to collapse the shoulder.
I had an idea in my head since the day I made the old one. So a quick dig in the Scarp Bin and this old timer was found.

Nice soft M16.
The idea was to drill it out to accept a M6 cap screw to butt up against a shoulder at the bottom and then use the M16 nut to collapse the riv nut shoulder. the bits I wanted.

I ended up making this modification after the first try with the new tool. A small recess for the riv nut's flange.

The complete assembly before tightening the M16 Nut. The friction was more from the M16 nut to the angle iron base plate so I ended up turning the bolt part of the tool. I machined 2 flats on it to accept a 14mm spanner.

And to show it works...Take note of the number of turns required for the desired end result. Turn toooooo much and the whole thing just collapses in a skew mess. This was after 2 full turns.
