not sure what to do with this bolt. It looks like it needs a special narrow nut or something, not sure how I am going to get 1-3 threads past the nut. Any ideas?
Gotta be a defect. The grip length (distance from bottom of bolt head to beginning of threads) should be 3 11/16" for AN6-42 if I am reading my chart right. I'll bet yours measures longer. I think you can even see where the grip stops and the threads should go to, but don't.
It's a little hard to tell from the spec, but it seems that the threads must be at least 7/16" long on an AN6 bolt.
I just measured two that had cotter pin holes drilled. From the good thread at the root to the hole was 3/8" and to the tip end of the thread (from the root) was 1/2".
On mine, an MS21042 nut fit okay for length, and is an approved replacement to AN365 nuts.
I'd be tempted to call them and send yours back for a replacement.
