The Dzus fasteners need to be installed with special dies, one for the grommet and one for the “screw” itself. When I was at Oshkosh, I found this out and found a place ot order the dies from. I was told it was back-ordered and should be shipping in 3 weeks. I was told this every month for the past 5 months. I was starting to get desperate, and I had the good fortune to mention my problems to Henry Rise at Midwest Sky Sports, who lent me his dies and C-clamp (it takes a special C-clamp to use the dies). THANKS HENRY!!!!

The process is pretty simple. First you put the grommet in the hole, making sure it is the correct direction. Then you use the first set of dies to flare the grommet just a little bit, so it doesn't fall out of the hole. It should still jiggle around in there. I found it took about a half turn of the C-clamp once the dies made contact.

After that, the screw goes in and the dies are changed. I found that it took about a 3/4 urn of the C-clamp once the dies made contact to set the grommet the rest of the way in, which means that it was no longer jiggling in the hole and the screw could not come out. The first Dzus connector took me about 10 minutes and the third one (the last one) took all of 2 minutes. Kind of anti-climactic after waiting so long, but I am OK with that!

If you want to see a video that looks like it is from the 1970s (ie, 50 years ago!), this is the one I used. The person in this one used a hammer rather than a clamp, but the process is the same. - https://youtu.be/zlBlAEFcTRA
