Typically, commercially available mild steel all thread rod will not meet the requirements of F1554 grade 36. Most all thread rod that is readily available in the marketplace will typically meet the requirements of ASTM A307 Grade A. The difference between these two specifications is that F1554 Grade 36 anchor bolts have a minimum requirement for reduction of area (a value associated with the steel’s ductility), whereas A307 does not. Therefore, the test reports that accompany A307 all thread rod will not contain a reduction of area value and therefore cannot be certified to meet F1554 grade 36.
Portland Bolt stocks domestically manufactured mild steel all thread rod conforming to F1554 Grade 36, both black and galvanized, that has undergone reduction of area testing, and these values are reported on the accompanying test reports.
