It is envisaged that when the full range of European Standards on technical drawing is implemented BS 308 will be withdrawn.

21、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 establishes rules for the simplified repr

22、esentation 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 Normative references The follow

23、ing 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 inv

24、estigate 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.

The degree of simplification depends on the kind of object represented, the scale of the drawing and the purpose of t

26、he 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 shapes of screw heads, drive patt

27、erns 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.EN ISO 6410-3:1996 4 BSI 10-1998 Table 1 No. Designation Simplif
