I used the Fastenal bit I linked to earlier in this thread (sounds like the same one you are using). Unfortunately, I don't remember the diameter I measured for the AN6 bolt. My experience was the same as Corby202--only had to tap the bolts in when installing on the airplane.
I occasionally shake the airplane by the wingtip to see if there's any looseness and I haven't noticed any.
Chris,
Do you still have the Fastenal bit and would you be willing to loan it out? At the rigging stage now and getting everything set up for drilling. Thanks.
