Here you go
The rivets used in RV construction are 2117 Alloy "AD" rivets. See the milspec chart, which will give you some shear strength data. Its not the greatest chart, because it doesn't take into account variations of dimpled and countersunk stack-ups. In real world structural repair manuals, often the guidelines revolve more around minimum skin thickness for countersinking, which has a profound affect on joint strength, IE, you never want a knife-edge condition. Dimple joints do give some additional strength and durability because the skin bearing strength added in the "clinching" of the joint. When I built my -4, I used single piece upper skins of .032" (minimum thickness for 3/32"rivet CSK)and eliminated the mid-span joint. My skins are countersunk, as well as my vertical and horizontal skins, which are .032" The leading edges are dimpled. 11 years of harder than average flying, not one single "smoking rivet".
