I used 1/4” brass aircraft nails from Aircraft Spruce. They were cheap enough and are resistant to corrosion. A bit tricky to handle due to their size but I found that a pair of spring action tweezers helped with that. 

Of course, you could always make do with no nails at all - the only thing they really do is hold the gussets in place while your glue dries. Using the nails means you don’t have to leave the ribs clamped in place while waiting for the glue to tack. I considered doing without, but I calculated that the nails used in all of my ribs would add less than 1/4 lb to the total weight of my Pietenpol. A good trade off in my mind, all things considered. 
Hope this helps,

I am once again returning to building some ribs after a long absence and honestly I don't have that many to go (relatively speaking). Looking at the plans I see the notation "nailed and glued on both sides of wing rib 1/2" 20 ga nails". 


Is anyone using brass plated "Escutcheon Pins"? Stainless nails? Help!


Any an all input is appreciated.

I used no nails at all. I used common pins nailing them lightly and removed them after epoxy sets.

Hi Brian, just weight the gussets down, it works real well and doesn't perforate the capping strip as does a nail!
I've used lead shot in aerosol can caps and very small dumbbell weights as examples, I've also seen concrete in plastic caps used.

It depends on what glue you are using. If using epoxy, as most do these days, no nails are necessary other than to simply hold the gussets in place as the epoxy cures (as other have mentioned). Many people have used staples (and some will then go back and pry out the staples after the epoxy cures). If using resorcinol, it is necessary to have a clamping force of at least 75 psi, which requires a nail about every ”. I used resorcinol, and used ” AN501 nails from Aircraft Spruce. These nails are brass plated.
