Is this a specialty bolt?

Is this a specialty bolt?

Is this a specialty bolt?

(OP)
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?

RE: Is this a specialty bolt?

This bolt is available. Try http://www.usmilitaryfasteners.com/an/an21-36.htm

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).

Cheers
