Description / Abstract:
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.
The values stated in SI units are to be regarded as the
standard.
