It is identical with ISO 6410-2:1993 published by the International Organization for Standardization (ISO). This British Standard partially supersedes BS 308-1. It is envisaged that when the full range of European Standards on technical drawing is implemented BS 308 will be withdrawn. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 1996, and conflicting national standards shall be withdrawn at the latest by October 1996. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

Requirements within industries vary considerably; in recognition of this fact, ISO 6410 is presented in three parts. 1 Scope This part of ISO 6410 specifies methods for the representation of screw thread inserts on technical drawings. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 6410. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 6410 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 128:1982, Technical drawings General principles of presentation. ISO 6410-1:1993, Technical drawings Screw threads and threaded parts Part 1: General conventions. 3 Representation 3.1 Detailed representation of the true shape of screw thread inserts The detailed representation of the true shape of screw thread inserts (see Figure 1 to Figure 3) shall only be used for illustrations, e.g. in catalogues, and should be avoided in technical drawings. Figure 1 Figure 2 Figure 3 3.2 Conventional representation Screw thread inserts are usually drawn using a conventional representation derived from ISO 6410-1. The outer forms of screw thread inserts vary greatly depending on the intended purpose, the material, the manufacturer, etc., and may not even be threaded, but all shall be depicted in the same way. Examples are shown in Table 1. 3.3 Simplified representation In simplified representation only the essential features shall be shown, depending on the kind of drawing and the purpose of the documentation. The simplified representation for screw thread inserts should be used whenever possible. The principle of simplification is shown in Figure 4. Different examples and possible identification for simplified representation of inserts are shown in Table 1. In sections, the outlines of the screw thread insert (external and internal crests) shall be shown by a continuous thick line (type A, ISO 128). The nominal diameter of the internal thread in assembled condition shall not be shown. The insert itself shall not be hatched (see Figure 5). On an end view, the external and internal crests shall be shown as a full circle by a continuous thick line. The nominal diameter of the internal thread in the assembled condition shall not be shown (see Figure 6).

If such standards are not available the designation shall consist of the designation for the thread, d × P (screw thread for which the screw thread insert is intended) followed by the letters INS (for insert). EXAMPLE M30 × 1,5 INS When a more general description is sufficient, e.g. there is an insert placed, the abbreviation INS shall be indicated (see Figure 5 and Figure 6). NOTE 1If the thread is coarse, the designation of the pitch, P, may be omitted. Additional information (manufacturers name, catalogue number, etc.) may be added. The designation may be indicated by means of a leader line (see Figure 7) or as a dimension (see Table 1).
