Bolt threads - shank "shouldering"

[Wayne G. O'Shea]

That's exactly what I use to suggest to everyone as a bench mark Jesse
before starting. Shoulder a nut on purpose and carry on from there. (Keep
one around for the inspector in Canada guys for when they tell you too many
threads are showing!) This also becomes of great importance when you attempt
to install a prop with normal thread length AN bolts instead of the prop
bolts with the 1" + threads instead.

I read this and got scared, so just went out and looked at my second wing
that is nearing completion. My spar cap bolts all have only 2 washers

under

the nut and none under the head. I have 3 whole threads showing. To

reassure

myself I just tightened a nut on an AN3-7 gently until it shouldered. I
counted 4 1/2 threads showing. I am satisfied I have a good installation.

All you are shooting for Jean is in 1 thread showing and max 2 1/2 to
3..but
be careful on those AN3's as three threads is pretty carn close to
shouldering the nut. No need for a washer under the heads unless you are
turning the bolt....although I do remember the AN3 bolts supplied for the
spar cap section needed 1 under the head and two under the nut so they
weren't shouldered.

No matter what the case, I sure wouldn't be playing with the Prosealed
ones!

Hello everybody,

I have just discover that I have missdone a job on my first wing.

For the AN3 bolts that fix the spar cap on the main spar, I have put

washer (1-2) under the nut, but non under the bolt head!

Easy to fix for the primered section but for those in the wing

tank.....

Should I remove the proseal to make the change (the top skin not riveted
yet
(for inspection)?
