1、BRITISH STANDARD BS EN ISO 10511:1998 Prevailing torque type hexagon thin nuts (with non-metallic insert) The European Standard EN ISO 10511:1997 has the status of a British Standard ICS 21.060.20 BS EN ISO 10511:1998 This British Standard, having been prepared under the direction of the Engineering
2、 Sector Board, was published under the authority of the Standards Board and comes into effect on 15 May 1998 BSI 04-1999 ISBN 0 580 29082 4 National foreword This British Standard is the English language version of EN ISO 10511: 1997. It is identical with ISO 10511:1997. The UK participation in its
3、preparation was entrusted by Technical Committee FME/9, Bolts, nuts and accessories, to Subcommittee FME/9/10, Male and female prevailing torque fasteners, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries
4、 on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Attention
5、 is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement international or European publications referred to in this document may
6、be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British St
7、andards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

20、dards3 EN ISO 10511:1997 ii BSI 04-1999 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 bo
21、dy 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 Electrot
22、echnical 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 v
23、ote. International Standard ISO 10511 was prepared by Technical Committee ISO/TC2, Fasteners, Subcommittee SC 1, Mechanical properties of fasteners. Annex A of this International Standard is for information only. Descriptors: Fasteners, nuts (fasteners), self-locking nuts, hexagonal nuts, specificat
24、ions, dimensions, designation. EN ISO 10511:1997 BSI 04-19991 1 Scope This International Standard specifies the characteristics of prevailing torque type hexagon thin nuts (with non-metallic insert) with thread from M3 up to and including M36, in product grade A for threads up to and including M16 a
25、nd product grade B for threads above M16, and with property classes 04 and 05. NOTEThe dimensions of the nuts correspond to those given in ISO 4035 plus prevailing torque feature. If other specifications are required, they should be selected from existing International Standards, for example ISO 261
26、, ISO 965-2, ISO 2320 and ISO 4759-1. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
