The ?Remarks? and ?Informative references? underlined with dots are items not included in the original International Standard. JIS B o002 has been devised to provide a universal means of communication among the various interests involved in the design, manufacture and installation of fasten- ers. 1 Scope This part of JIS B 0002 specifies methods for the representation of screw thread inserts on technical drawings. 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 Figs. 1 to 3) shall only be used for illustrations, e.g. in catalogues, and should be avoided in tech- nical drawings.

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 Attached 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 Fig. 4. Different examples and pos- sible identification for simplified representation of inserts are shown in Attached Table 1.

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