MS20365's are the same part. Why change.
They are freely available at most suppliers.
ALSO, Irv designed neat airplanes but unless you
show somebody HOW the bolt is used, asking
about substitutions on the net isn't where I'd
get the answers.

I am working with 40 year old plans that call out AN365-6 Nuts.
Since they are used in conjunction with AN6 Bolts (24 of them) to
attach the main spars together, I am assuming they are locknuts.
Is the AN363-624 Metal Lock Nut a good match or good substitution?

Gotta have something to hold 49 feet of wings together.
