The short answer is no. The reasons behind the answer are a little more complicated. The F3125 Grades A325 and A490 specification is designed for headed fasteners intended for structural applications only. These two grades cannot be manufactured in any configuration of fastener. Because these two specifications are used for headed fasteners only, both are not available in an all thread rod configuration. For all thread rod with similar strength characteristics to A325, you can look at substituting A449 or A354 Grade BC depending on the diameter of the material; for an A490 all thread rod equivalent, the F3125 specification states to move to A354 Grade BD. Any grade substitution should be approved by the Engineer of Record.
