"The general expressions for threaded parts in Table J3.2 give the design strength (LRFD) or allowables (ASD) as a function of Fu."
 
Thank you for your response. There are two grades of A354 steel: BC and BD. A490 is equivalent to A354-BD. Table J3.2 does give the allowable stress of A490 bolts as 54 ksi in tension, which is different to 0.33Fu=49.5 ksi. On the other hand, A354-BC and A687 have no equivalent in the table. Please clarify what are the correct values.

According to Table 1-C (page 4-4 of the ASD Manual)

A more up-to-date list of recommended anchor rod materials is here:
 
 
The general expressions for threaded parts in Table J3.2 give the design strength (LRFD) or allowables (ASD) as a function of Fu.
