Title
Standard Specification for Headed Steal Bars for Concrete Reinforcement
ASTM International
Publication Date:
Oct 15, 2007
Scope:
This specification covers deformed and plain steel reinforcing
bars in cut lengths, with a head attached to one or both ends, for
concrete reinforcement. Attachment can be accomplished through
welding, by integrally hot forging of a head from the reinforcing
bar end, by internal threads in the head mating to threads on the
bar end, or by a separate threaded nut to secure the head to the
bar. Heads are forge formed, machined from bar stock, or cut from
plate.
NOTE 1—This specification is applicable for headed bars produced
with welded, threaded, or forged heads and used for reinforcement
of concrete structures. The requirements of this specification are
not applicable to headed bars where the attachment of the head is
accomplished by alternate means.
This specification is applicable for orders in either SI units
as Specification A 970M or inch-pound units shown in the text in
brackets [Specification A 970].
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in non-conformance with the standard.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
*A Summary of Changes section appears at the end of this
standard.
