RV-6 rear spar bolt

[BruceMe]

For posterity... by my measurements, this is the appropriate bolt;

AN5-7 is the normal tolerance bolt, you can undersize and ream to match

or

NAS6205-8D

is the close tolerance equivalent.

A/S doesn't sell the "D" (drilled) version so you'll have to drill it.

If you don't want to drill the cotter pin hole yourself, there are other sources...

Thanks to all for the info. This site is worth it's weight in gold! I will buy the bolts but I cannot install until I put the wings back on. They are at the airport anxiously waiting the arrival of the fuselage.

Do you need a castle nut? I thought that those were only for pieces that moved? I can't remember what I used, but I am certain that it what was called out for on the plans.

That joint does move a little. Effectively, it is a pivot point that moves a little bit under load.

So you do want a castle nut there.
