    High strength bolt installation question

    A new building is going up. I'm looking at the bolting of the structure. They are A325TC bolts and A490. When they install them, are they required to have the nut identification markings on the outside of the connection? Is that in the ASTM book? I'm looking now and haven't run across it...
