Introduction IS0 6410 has been devised to provide a univerd means of communication among the various interests involved in the design, manufacture and instailation of fasteners. Requirements within industries vary considerablx in recognition
17、of this fact, IS0 6410 is presented in three Parts.

The degree of simplification de- pends on the kind of object represented, the scale of the drawing and th
22、e purpose of the documenta- tion. 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
23、 screw heads, drive patterns or nuts, the examples of sim- plified representations shown in table1 shall be used. Combinations of features, not shown in tablel, may also be used. A simplified represen- tation of the opposite (threaded) end view is not necessary. CEN EN*ISO*b430- 3 96 3404589 0334557
