Attached is a picture of my bolts/washers. There wasn't even a question of using them again!

I wouldnt reuse the stock washers under any circumstance, they are dead soft and need to be in order to be able to deform them as that type of lock.
Its the deformation of the washer under stress that causes the failure, reuse is about the worst thing that can be done.

I would use a proper ground grade 8 washer and the loc-tite and never worry again.

I agree to remove all locking plates.
Be careful not to use a thick washer, because thats less threads into the carrier. I don't use any washers, I just tighten & using the "red" (strongest) thread locking liquid. Either way is fine

If it was me I'd be using the AN/NAS bolts with a thin an washer and probably safety wire them!

The 1/4" of shoulder is required to get a good uniform bearing for each bolt around the ring. Many store-bought Grade 8 bolts that short are threaded all the way to the head, which means the ring gear would be bearing on points of thread instead of a continuous surface.

While bolt strength is important, the main issue is the elimination of play.

The bolts called out above are both short, tough (which is sometimes better than hard), and have a short un-threaded segment at the head. All good, except they're slightly too long, and would bottom out. Can't stack up washers, so you have to trim. I used my milling machine, and they cut pretty easily. I did end up using hard flat washers, and red Loc-tite to finish out the repair. Pending install, though...
Good info, Thanks
