These TOX spiral pro plasterboard dowels were sent to me by Paul EKstorm-Hughes from Sweden a few years back. I finally found the time to test the fixings out in some 12.5mm plasterboard. I have to say that the fixings are very easy to use and performed much better than I expected.
Here is a link to them on Amazon (I’m not on commission) https://amzn.to/3aMo07O
If you want to know which plasterboard fixings can hold the most weight, I have done several tests over the years, all of which have been collated into a single forum post here- http://www.ultimatehandyman.co.uk/forum1/viewtopic.php?f=1&t=106943
