What size rivnuts to attach to Trillium interior?

[neilff]

I'm looking at attaching a small cargo mesh frame to the interior of our 2020 Trillium. I've been told to look at using rivnuts.

Ended up buying some on Amazon however I'm not clear on what size nut to use for the thickness of the fiberglass. It seems like they only support very thin materials. I was hoping to use an M4/5 but that might be too tiny for what I believe is 1/8 thick walls.

Anyone with experience doing something like this? I'm curious what size you used.

I just used some from Home Depot in 8-32 size but they have 6-32 and 1/4 inch as well. The 8-32 size require a 1/4" hole in the fiberglass. They sell the inserts as well as a simple kit with the inserts. I did have some problems with the tool with not enough friction to keep the rivet from turning so filed some deeper groves in the tool and found it worked better. Check with the store to make sure they have in stock as a couple of local stores didn't have them. https://www.homedepot.ca/product/pau...num/1000162982
