You shouldn't need to access to back of your panel! That is the beauty of the rivnut. I bought aluminium ones from local fastener, m4 from memory. I used a set of engineers callipers to get drill size. Drilled holes and used rivnut tool and viola, you have it all ready to go!Quote:

Hmmm, I did the install today but not happy. The rivnuts I have been supplied have a plain outer surface (there are no ribs that crush), and they just pull out.
I tried the method described in the link but was not v successful - the theory seems wrong to me... i.e. when tightening the nut on the bolt it pushes me up, rather than the rivnut down. Make sense...? I had to tap them in
Anyway, now how to solve? :confused:
Kerching!
OK i just youtubed and ive completely misunderstood how these things work - thought they were an inteference fit but they actually crush/ splay behind the panel and are therefore retained...?
Hopefully all is not lost...
They are called rivnuts because you set them with pliers much like a pop rivet tool. Doing them by hand (nut-and-bolt method) is OK so long as they don't squidge out the front of the panel they are in. I made a hand-held tool once, the main thing was a sharp recess to retain the top of the rivnut as you did up the setting nut. You can easily make a hand tool, you need a drill bit exactly the OD of the rivnut flange, sharpen it so it cuts with two raised points not the normal shape, (basically a shallow W shape so the centre still locates) and drill a shallow circular groove into a piece of flat bar to use as a hand hold.
Well it was easy in the end - like the tutorial says, should take about a minute each...
Apart from that I got 9 crimped up OK and 1 of them not quite hard enough... the spinning rivnut :mad: Couldnt get the bolt out, had to cut it off with the angle-grinder, v difficult, right next to the bonnet/bullbar, damaged the checkerplate :mad::mad::mad:
Now i'm left with a loose rivnut that i cant get out and probably cant tighten back up. Suggestions?
Can you post up a photo? Might help with the solution...sounds tricky.
