They have become a lot less evil since I got myself a couple of these from eBay:

They are nicely made and I find them easier to use than the collection of nuts & washers that I used to use.
The adjuster nut thread is coarser than the rivet thread which enables efficient & speedy tightening.

Not too expensive for a tool that will last a lifetime. Just search eBay for 'Engineers High Tensile Rivnut Setting Tool'.
