MK-319 BS
Van recommends MK-319 BS for 3/32 (AN426-3) replacement in the wing walk area if you can't get your hand in the close fit ribs to buck the AN426 rivets. The MK-319 BS has the same head diameter and is a flush rivet.
You do have to drill the hole bigger, #35 or so. Vans says to drill 7/64ths.
I just stuck the rivet in the drill gauge, and picked the smallest hole the rivet would easily fit. I used that drill to increase the #40 drilled hole, then installed the MK-319BS.
Cherry makes a 3/32 pull rivet that is accepted for holding platenuts, but platenuts are held in place by the fastener when under load, so the rivet isn't really used as a structural part in this application. Also, Cherries are more expensive than Van's offerings. Still, driven rivets are so much cheaper, stronger, and have a better finish that it's well worth our time to learn how to use them as much as possible.
Opps! I posted this too slowly and several guys beat me!!
