Does ASTM F1554 require headed anchor bolts to be head stamped with the fastener’s grade symbol and manufacturer’s logo?

Permanently stamping the headed end of F1554 anchor bolts is not required or detailed in the ASTM Specification. Portland Bolt chooses to stamp the headed F1554 anchor bolts that we produce in order to provide an alternative way to identify the bolts before the headed end is embedded in concrete. Anchor Bolts are marked on the threaded end that projects from the concrete with a designating color code, per the F1554 specification. Marking the threaded end that protrudes from the concrete with paint allows engineers and inspectors to identify the grade of anchor bolt that is embedded in the foundation. Permanently stamping the threaded end with the grade identifier and manufacturer’s logo is a supplemental requirement and needs to be specified on the inquiry and purchase order.
