The document discusses specifications for anchor rods, base plates, and embedded plates according to various ASTM material standards and AISC provisions. It addresses questions regarding acceptable material specifications and configurations for anchor rods, preferred hole sizes in base plates, requirements for washers, acceptable methods for extending short anchor rods or welding rods to base plates, and considerations for accounting for base plate distortion and providing grout holes. Acceptable threads can be rolled, cut, or ground. Anchor rods should not be welded to base plates if intended to provide erection stability. Hooked rods are not recommended for uplift resistance.
