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of an identical text or by endorsement, at the latest by October 1996, and conflicting national standards shall be withdrawn at the latest by October 1996. Accor

23、ed to provide a universal means of communication among the various interests involved in the design, manufacture and installation of fasteners. Requirements within industries vary considerably; in recognition of this fact, ISO 6410 is presented in three parts. 1 Scope This part of ISO 6410 establish
24、es rules for the simplified representation of threaded parts, with the exception of screw thread inserts, which are covered in ISO 6410-2. This representation is applicable when it is not necessary to show the exact shape and details of the parts (see ISO 6410-1), for example in assembly drawings. 2
25、 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 o
26、f 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 225:1983, Fasteners Bolts, screws, studs and nuts Symbols and designations of dime

ISO 6410-1:1993, Technical drawings Screw threads and threaded parts Part 1: General conventions. 3 Simplified representation 3.1 General In simplified representation only essential features shall be shown. The degree of simplification depends on the kind of object represented, the scale of
28、the drawing and the purpose of the documentation. Therefore, the following features shall not be drawn in simplified representations of threaded parts: edges of chamfers of nuts and heads; thread run-outs; the shape of ends of screws; undercuts. 3.2 Screws and nuts When it is essential to show the s
29、hapes of screw heads, drive patterns or nuts, the examples of simplified representations shown in Table 1 shall be used. Combinations of features, not shown in Table 1, may also be used. A simplified representation of the opposite (threaded) end view is not necessary. Licensed Copy: sheffieldun shef
