Is this a specialty bolt?

[CRG]

I am not having any luck finding a 9/16 clevis bolt with a 3-11/16 grip. I have looked on the internet and could not find a table showing an AN29-?. All of the suppliers that have tables listing clevis bolts seem to drop off at around 1/2” diameter. Is there a specification that lists all of the AN hardware dimensions that can be downloaded for free. I need this information for a personal aircraft and being that my area of engineering practice has nothing to do with aircrafts, buying a spec to lookup one bolt seems like overkill. This particular bolt comes from a classic aircraft where there is no longer a manufacturer to provide support. If this is a standard AN bolt, does anyone have a recommendation where to purchase 8 EA of these?

Can you use an NAS close tolerance bolt instead?
Or do you have to have the round head on the bolt?

Your clevis bolt is AN29-66, 4130 alloy steel, cadplated. You might be able to find the right size clevis pin or shoulder bolt (.560")to replace this. I belive the minimum buy is 13 bolts ($100).
