The area where he is placing the screws is in structural fuselage
tubing. I feel that the hole size required for rivnuts might
compromise the integrity of the tubing. He is adding a new set of
holes as it is. Best to get some number sized drill bits ( 1/64" one
way or the other may not work ) and practice on some scrap tubing to
find the one that works.

Gotcha, Bob. Mebbe he just needs one those rare "sheet metal screw" taps???

Rich,

Now that you mention it, a self-tapping sheet metal screw of some type
might work.
