Do headed F1554 anchor bolts need to have their forged heads stamped with the grade or manufacturers’ identification?

ASTM F1554 requires the end that projects from the concrete to be marked with a grade identification marking, which, unless otherwise specified, is blue, yellow, or red spray paint on the projecting end only. If a supplemental requirement is specified then the projecting end will be stamped with a grade stamp and/or a manufactures’ identification stamp.  The embedded end does not need to be marked in any way.  Since a headed anchor bolt functions with the forged head being embedded into concrete the head thus has no marking requirement and instead the threaded end receives spray paint or a stamp.
