I was installing bolting the inbaord hinge-bracket/bearing assembly to the rear spar of the HS today. The plans called for AN3-5A bolts, AN960-10 washers and AN365-1032 nuts.
These parts weren't labelled explicitly in the stuff from Vans, but there was a bag which was labelled in the parts list as "AN3 Hardware". Inside I found bolts washers and nuts. I verified the bolts to be AN3 with my bolt gauge and selected ones with a length of 5.
Questions:
1) Were these the right bolts? What does the final "A" mean an AN3-5A ?
2) The nuts in the bag were all identical, they all had white plastic inserts in them. Are these the AN365-1032 nuts?
So I went ahead and used these parts. I set my torque wrench for 20in-lbs, and began to tighten them. The torque wrench never released (although I've never used a torque wrench so I'm only guessing what this would feel like. What happened was that the nuts eventually got to a point where they turned sort of freely, without tightening on the bolt anymore. This made me wonder...
3) Do these nuts somehow self-torque with those plastic inserts? Should I be worried that they stopped tightening before 20 in-lbs, when the guidelines say AN3 bolts should be torqued to 20-25 in-lbs?
If I'm correct in my hypothesis about the nuts self-torquing, one more question...
4) How much damage to those nuts can result if I keep turning them once they have stopped tightening? Should I replace them?
Thanks!
Phil
