I need to install rivnuts in a 1/4" aluminum plate. I bought a Wetol rivnut tool from Amazon which came with a bunch of nuts and I'm trying to figure out which size to use. The sizing instruction seems a bit confusing (image attached)
There are 2 grip ranges mentioned for each nut size. How do I figure out which size to use for the 1/4" plate and the relevant hole size to drill ?
Thanks
