I'm getting close to finishing up the wing leading edges, and I need to drill out the holes for the wing tie-downs. I have two options... drill it out to 3/8 (plus some breathing room) for just the tie-down bolt, or 11/16 so I can pass a jam nut tight to the tapped aluminum. 



Opinions?

My plane is hangered most of the time so I take the tiedown rings out most of the time and thus no jam nuts

I too carry mine with me, install as needed. I do this under the delusion that it gains me huge amounts of extra speed (!). OTOH the tail ring is in all the time.

Ed,  I intend to "lock tite" mine into the tapped AL threads.  I also had mine chromed so they are staying in the wing cause they look so good!

I take mine out. I think it gives me about 23 kts extra speed

by removing them.

I wonder if that is a "Van's approved" speed mod!

I use the tail hook as my rudder trim and even that gives me a bump in performance. 



But I install my S/S wing tie down bolts as needed.

I painted them white to match the       wing.  The paint gummed up the threads just enough to eliminate       the need for jam nuts, just as I planned.

Thanks everyone! Sounds like I won't need the jam nuts even if I do leave them in... which I probably won't. 



On the other hand, I am going to permanently attach my tail tail down. Wouldn't want the rudder fairing taking damage if a tail strike were to happen...

Mine all had a slight gap between skin and tiedown. You can fill that gap with proseal, use an o-ring and locktite. I just leave my SS eyebolts in all the time. If the gap is not filled you will be puckering the skin upon tightening.
