A563 nut grade for F1554 Gr 55 2

[X4vier]

Hello,

I can't find an AISC or RCSC reference for the nut grade required for a F1554 Gr55 Anchor bolt.

Even Design Guide 1 says grade A, but it looks inadequate.

I appreciate any help you can provide.

I was thinking the F1554 standard showed what nuts to use.

If I am remembering correctly, the spec lists acceptable nuts and washers.
I think it is A563 Grade A nuts for all but F1554 Gr. 105 (which requires A563 Gr DH). I spec Heavy Hex.
