This European Standard was approved by CEN on 14 July 2019.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

1 Scope
This document is the configuration master for the content and structure of externally threaded fastener
product standards.
This document
— defines the content of externally threaded fastener product standards;
— is referenced in product standards;
— defines part numbering and title.
This configuration master defines externally threaded fasteners, metric and inch series.
