Products and versions covered . The extract given in Table 15.1 from the standard gives thread sizes from 1.6 to 24 mm diameter. *The pitch of 1.25 mm for 14 mm diameter is to be used only for sparking plugs.The thread pitch is the distance between corresponding points on adjacent threads. The correct representation of threads in technical drawings (whether it is an internal or Außengewinden act) is to DIN ISO 6410-1.
For preference, choose the diameters given in Column 1. This part of ISO 6410 specifies methods for representing screw threads and threaded parts on technical drawings. Schematic representation 3. insert, model items. Learn The Art of Pencil Drawing From The Experts.
