I'm currently using:

really its too large a diameter though not a serious issue but is too
thin where it distorts badly whilst welding a nut in the centre.

Are there any off-the-shelf sources I can obtain a couple of these that
are 2-3mm thick? I've run out of ideas!

Thanks for the ideas.

Going for a 1.5mm thick washer M10 x 50mm and a rivnut from eBay.

The clinch nuts, do they go through the sheet, then get the thin part belled out like a rivet?
