Actually, one thread is enough.  And I have an A&P/AI that says as long as a thread is protruding somewhere around the nut, there is enough threads engaged to be safe.  

Good luck on your first flights!!!!

  Hello,

   

  I am sooooo close to flying ... but little things keep popping up.

   

  Today we were attaching the wings and ran into some difficulty.

   

  I used factory supplied bolts (which only have one one-half inch of threads.  As instructed, I used two washers - one on each end, then attempted to tighten down the lock nut.  BUT ... after tightening the bolts all the way down and running out of thread, the bolts still rotated in the holes and the wings were not snug. 

   

  As a solution, I added one washer to each bolt.  This made it possible to snug down the wing and torque the bolts as recommended (30 to 40 ft. lbs).  It also made the bolts good and tight with no rotation.  However, the bolt tips are now even with the lock nut and do not extend through the end.  I was always told that you need at least three threads sticking beyond the end of the lock nut.  Is this going to be a problem?

   

  The only way I can get three threads beyond the lock nut is to use bolts that have more threads on them.

   

  Many of you have moved past this point ... so your help and advice would be greatly appreciated.

   

  Tom
