Luis - the way the fittings are designed to load the bolts in shear only
looks to me like the nut is there to keep the bolt from backing out and
no clamping pressure is considered in the design of the joint. My glider
has its wings retained by a couple of big shear pins with spring clips
to keep them from moving out, and my V-Witt's flying and landing wires
have clevis pins with cotter keys to keep them in place - NO threads
whatsoever,so zero clamping force/torque value, yet all flying and
landing loads go through them. So designing a joint like this with no
specified torque value on the bolt is probably because the bolt is used
as a pin only.

Just finished attaching my wings on permanently and need to torque the bolts
and place my cotter keys. Researching the torque value of an AN6 bolt I found
that 95 in pounds. I researched the newsletters and could not find a remedy so
here goes my question...
Thanks
