Types of Finishes

F1554 Grade 105 anchor bolts can be manufactured in plain (black), mechanically galvanized, zinc or hot-dipped galvanized finishes, as well as (or along with) others as per your request. The act of galvanizing will not create hydrogen embrittlement. AA Anchor Bolt, Inc. works with various facilities for quality assurance and quick turnarounds.


F1554 Grade 105 cannot be welded. F1554 Grade 105 develops its strength characteristics when it is quenched and tempered (heat treated). Welding or applying heat to F1554 Grade 105 material will change the mechanical properties of the anchor bolt. According to the Ninth edition of the American Institute of Steel Construction (AISC) Steel Construction Manual (page 4-4). “Anchor bolt material that is quenched and tempered (heat treated) should not be welded or heated.”
