AISC's LRFD Sec. Ed. Vol. II states "...ASTM A325 Type I high-strength bolts
and A449 boltsare permitted to be galvanized; A490 bolts are not permitted
to be galvanized."
This is on Page 8-18 of the LRFD manual. It also describes mechanical vs.
hot-dip galvanizing in short, referring the reader to AISC (1993). ASTM B695
covers mechanical galvanizing and ASTM A153 covers hot-dip galvanizing..
So, it looks like its fine except for A490 bolts, just choose a galvanizing
method. Hope this answers your question fully--
