Those are AN3 bolts. I have a similar setup. It has a nutplate on the back inside the cockpit, and there are washers under the heads of the bolts.

The mount is made to be secured to the Firewall with 1/2" AN bolts but the plans show a "Rand Mount" that uses smaller (4) bolts on each of of (4) small pads. The bolst pas thru the SS, fiber Fax, 1/4" Firewall and the 5/8" thk boards. My question is the Washers, spacers and etc. to be used as O find callouts on the dwg or pictures either. Searc of KRnet turned nothing either Can anyone advise?
