Keeping Standards up-to-date
Australian Standards® are living documents that reflect progress in science, technology and
systems. To maintain their currency, all Standards are periodically reviewed, and new editions
are published. Between editions, amendments may be issued.
Standards may also be withdrawn. It is important that readers assure themselves they are
using a current Standard, which should include any amendments that may have been
published since the Standard was published.
Detailed information about Australian Standards, drafts, amendments and new projects can
be found by visiting www.standards.org.au
Standards Australia welcomes suggestions for improvements, and encourages readers to
notify us immediately of any apparent inaccuracies or ambiguities. Contact us via email at
mail@standards.org.au, or write to Standards Australia, GPO Box 476, Sydney, NSW 2001.

PREFACE
This Standard was prepared by the Standards Australia Committee ME-029, Fasteners, to supersede
AS 1111.1—2000, ISO metric hexagon bolts and screws—Product grade C, Part 1: Bolts.
The objective of this Standard is to provide manufacturers, suppliers and users with the dimensions,
tolerances and material requirements for hexagon head bolts of ISO product grade C with ISO metric
coarse threads.
This Standard is Part 1 of a two-part series on ISO metric hexagon bolts and screws. Part 2 gives the
dimensions for screws.
NOTE: The product grade refers to the quality of the product and to the size of the tolerances where grade A
is the most precise and grade C is the least precise.
This Standard is identical with, and has been reproduced from, ISO 4016:2011, Hexagon head bolts—
Product grade C.
As this Standard is reproduced from an International Standard, the following applies:
(a)
In the source text ‘this International Standard’ should read ‘this Australian Standard’.
(b)
A full point substitutes for a comma when referring to a decimal marker.
References to International Standards should be replaced by references to Australian Standards, as
follows:

Standards Australia
Standards Australia develops Australian Standards® and other documents of public benefit and national interest.
These Standards are developed through an open process of consultation and consensus, in which all interested
parties are invited to participate. Through a Memorandum of Understanding with the Commonwealth Government,
Standards Australia is recognized as Australia’s peak non-government national standards body.
For further information visit www.standards.org.au
Australian Standards®
Committees of experts from industry, governments, consumers and other relevant sectors prepare Australian
Standards. The requirements or recommendations contained in published Standards are a consensus of the views
of representative interests and also take account of comments received from other sources. They reflect the latest
scientific and industry experience. Australian Standards are kept under continuous review after publication and are
updated regularly to take account of changing technology.
International Involvement
Standards Australia is responsible for ensuring the Australian viewpoint is considered in the formulation of
International Standards and that the latest international experience is incorporated in national Standards. This role is
vital in assisting local industry to compete in international markets. Standards Australia represents Australia at both
the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
