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

The "two grip ranges" are associated with two different lengths in the right-most column.

The only sizes that offer a "grip range" including 1/4" (6.35 mm) is the 24mm M10s with 13.5 mm A dimension (13mm hole) and the 25mm M12 with 14mm A dimension (15mm hole.)
