Default Bensen hub bar question

I hope one of you out there can give me a little info. I have a set of Bensen/Brock blades and hub bar on my gyro. I wanted to change the bolts on the hub bar and blades and the bolts that hold the two together. I ordered standard AN 3/8th bolts but when I went to change them, I realized some of the bolts that are installed are NAS Close Tolerance bolts. Is there a requirement for these? Also I would like to replace the main teeter bolt, it is a standard AN bolt also, is that the correct bolt? I have looked through the gyrobee plans and online but I can not come up with which bolt types are correct.

Thanks,
Peter

Short answer...
AN 6-24 (3/8-24 x 1-15/16 GRIP, Bolt Hex) Rotor to Hub Attachments.

Be careful with washers. It should be the MS20002-6, 3/8x11/16, flat SPECIAL HIGH STRENGTH (red Edges)

Its the ones recommended by Bensen factory
