This specification covers the chemical, mechanical, and dimensional requirements, and associated test methods for straight and bent, headed and headless anchor bolts (also known as anchor rods) made of carbon, carbon boron, alloy, or high-strength low-alloy steel and having specified yield strengths. The anchor bolts are furnished in three strength grades, two thread classes, and various sizes, and are intended for anchoring structural supports to concrete foundations such as building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications. This specification, however, does not cover the requirements for mechanical expansion anchors, powder-activated nails or studs, and anchor bolts fabricated from deformed bars. The bolts shall adhere to specified elemental chemical compositions as examined by heat and product analysis. They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area. The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers straight and bent, headed and headless, carbon, carbon boron, alloy, or high-strength low-alloy steel anchor bolts (also known as anchor rods). The anchor bolts are furnished in three strength grades, two thread classes, and in the sizes specified in Section 4.
1.2 The anchor bolts are 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 similar applications.
1.3 Supplementary requirements are included to provide for Grade 55 weldable steel, permanent manufacturers and grade identification, and impact properties for Grades 55 and 105.
1.4 Zinc coating requirements are included in Section 7 for applications requiring corrosion protection.
1.5 The recommended grade and style of nut and washer are included in 6.6 and 6.7 for each grade.
1.6 This specification does not cover the requirements for mechanical expansion anchors, powder-activated nails or studs, or anchor bolts fabricated from deformed bar.
1.7 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
