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 Standards may also be withdrawn.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 which may have been published since the Standard was purchased. Detailed information about Standards can be found by visiting the Standards Australia web site at www.standards.com.au and looking up the relevant Standard in the on-line catalogue. Alternatively, the printed Catalogue provides information current at 1 January each year, and the monthly magazine, The Australian Standard, has a full listing of revisions and amendments published each month. We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. This Standard was issued in draft form for comment as DR 00036. AS 1110.1—2000 Australian Standard™ ISO metric hexagon bolts and screws— Product grades A and B Part 1: Bolts Originated as AS 1110—1972. Previous edition AS/NZS 1110:1995. Revised and redesignated, in part, as AS 1110.1—2000. COPYRIGHT © Standards Australia International ii PREFACE This Standard was prepared by the Standards Australia Committee ME/29, Fasteners to supersede AS/NZS 1110:1995, ISO metric precision hexagon bolts and screws, in part. The objective of this Standard is to provide manufacturers, suppliers and users with the dimensions, tolerances and material requirements for hexagon head bolts ISO product grades A and B 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. This edition has been technically revised and introduces the designations of product grade A and product grade B in place of the term ‘precision’ which has been used in previous editions. NOTE: The product grades refer 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 4014:1999, Hexagon head bolts— Product grades A and B. Statements expressed in mandatory terms in notes to tables and figures are deemed to be requirements of this Standard. As this Standard is reproduced from an International Standard, the following applies: (a) Its number does not appear on each page of text and its identity is shown only on the cover and title page. (b) In the source text ‘this International Standard’ should read ‘this Australian Standard’. (c) A full point should be substituted for a comma when referring to a decimal marker. References to International Standards should be replaced by references to equivalent Australian Standards, as follows: Reference to International Standard Australian Standard ISO AS 225 Fasteners—Bolts, screws, studs and nuts—Symbols and designations of dimensions — 724 ISO general-purpose metric screw threads—Basic dimensions — 888 Bolts, screws and studs—Nominal lengths, and thread lengths for general purpose bolts — 898 Mechanical properties of fasteners made of carbon steel and alloy steel 4291 Mechanical properties of fasteners made of carbon, steel and alloy steel 898-1 Part 1: Bolts, screws and studs 4291.1 Part 1: Bolts, screws and studs 965 ISO general purpose metric screw threads—Tolerances — 965-1 Part 1: Principles and basic data — 3269 Fasteners—Acceptable inspection — 3506 Mechanical properties of corrosion- resistant stainless-steel fasteners — 3506-1 Part 1: Bolts, screws and studs — 4017 Hexagon head screws—Product grades A and B 1110 ISO metric hexagon head bolts and screws—Product grades A and B 1110.2 Part 2: Screws iii ISO 4042 Fasteners—electroplated coatings AS — 4753 Fasteners—Ends of parts with external metric ISO thread — 4759 Tolerances for fasteners — 4759-1 Part 1: Bolts, screws, studs and nuts—Product grades A, B and C — 6157 Fasteners—Surface discontinuities — 8839 Mechanical properties of fasteners— Bolts, screws, studs and nuts made of non-ferrous metals — 8992 Fasteners—General requirements for bolts, screws, studs and nuts — 10683 Fasteners—Non-electrolytically applied zinc flake coatings — iv CONTENTS Page Introduction................................................................................................................... ........v 1 Scope...........................................................................................................................1 2 Normative references ...................................................................................................1 3 Dimensions...................................................................................................................2 4 Specifications and reference standards ......................................................................10 5 Designation ................................................................................................................10 Bibliography ................................................................................................................... .....11 Standards Australia Standards Australia is an independent company, limited by guarantee, which prepares and publishes most of the voluntary technical and commercial standards used in Australia. 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 national standards body. Australian Standards Australian Standards are prepared by committees of experts from industry, governments, consumers and other relevant sectors. 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 that 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 ISO (The International Organization for Standardization) and the International Electrotechnical Commission (IEC).
