This specification covers externally threaded steel anchor bolts intended for anchoring structural supports to concrete foundations.

Such structural supports include building columns; column supports for highway signs, street lighting, and traffic signals; steel bearing plates;

and other similar applications.

The anchor bolts are subject to tensile property requirements and are available in three grades (yield strength levels).

Special chemical restrictions apply when weldable steel is required.

Zinc coating (galvanizing) requirements are included for bolts requiring corrosion protection.

The recommended grade and style of nuts for each grade of anchor bolt are included.

This specification does not cover the requirements of mechanical expansion anchors or powder activated nails or studs for concrete.
