We strongly recommend against making any configuration substitutions without approval of the Engineer of Record. The term “headed anchor bolt” is somewhat ambiguous, but our interpretation of this product would be a bolt with a forged head, as opposed to a rod with a welded nut. If a galvanized, headed anchor bolt has been specified, there is a good reason the engineer chose that particular design. Making the decision to change configurations, or letting a bolt salesperson convince you that a rod with a nut is the same as a headed anchor bolt, could expose you and your company to a tremendous amount of liability.

What is the pullout strength of an anchor bolt?
We can provide you with the minimum strength requirements for a particular ASTM grade of anchor bolt, but you will need to consult with a structural engineer to determine the pull out strength of a specific size, grade, and type of anchor bolt. There are simply too many factors that affect the strength of an anchor bolt, including embedment depth, anchor bolt design, strength of the concrete, type of structure it is supporting, etc.
