Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 68-1 was prepared by Technical Committee ISO/TC 1, Screw threads, Subcommittee
SC 1, Basic data.
This first edition, together with ISO 68-2, cancels and replaces ISO 68:1973 which has been technically revised by
separating the metric dimensions from the imperial dimensions.
ISO 68 consists of the following parts under the general title ISO general purpose screw threads – Basic profile
— Part 1: Metric screw threads
— Part 2: Inch screw threads
