Prior to its creation, concrete anchor bolts were most commonly specified using the generic round bar specification A36 or the headed hex bolt specification A307. One end of each rod requires a permanent grade symbol and manufacturers identifier. With an L-shaped anchor the bent end is embedded in poured concrete, and on a straight anchor, one end with a nut and, possibly a washer (typically welded on) is embedded in the concrete. More information on F1554 anchor bolts is below. When hot-dip zinc coated anchor bolts are specified, Anthony Porreco, Sales Representative at Portland Bolt, A320 Grade B8 Class 2 bolts are strain hardened to achieve increased strength characteristics and reduce the potential for galling. We regularly receive drawings incorrectly specifying hex nuts be installed and tack welded in place on grade 105 anchor bolts. Anchor rods (or other configurations) that meet any of the three grades are color coded at the end that will project from the concrete to easily identify the grade used in the field (Grade 36: Blue, Grade 55: Yellow, Grade 105: Red).
