I've used my own home approach, which is similar. I used a nut with washers / spanner instead of that tool for all rivnut which are difficult to install using the normal tool :-)

Worked just fine on the steel one I just installed Chris!

Worked for all sizes and types for me.
I had one of the Memfast ones which is basically a glorified version of what you have shown there, it just has an integral spanner. It failed very quickly because during the tightening process the rivnut is trying to turn & the only thing preventing it is the serrations, these lose their bite very quickly when used with steel rivnuts which renders the tool useless.
I found that a strip of 3mm steel with a nut & bolt works the best, use a spanner on the nut to tighten it, another on the bolt head to hold it in position with the strip of steel. Once the bolt is worn you simply replace it with a new one, cheap as chips.

Ive had a Spiralux rivnut tool for donkeys years, its bent a bit, been straightened and still works fine. Came with an M8 mandrel also. Recommended.
Powerful do another tool which sets M4, M5 and M6 rivnuts.
