1. This standard establishes the rules for depicting and applying thread designations on drawings of all industries and construction.
The standard corresponds to ST SEV 284-76.
2. The carving is depicted:
a) on the rod - with solid main lines along the outer diameter of the thread and solid thin lines - along the inner diameter.
In images obtained by projection onto a plane parallel to the axis of the rod, a continuous thin line along the internal diameter of the thread is drawn along the entire length of the thread without a runoff, and in views obtained by projection onto a plane perpendicular to the axis of the rod, an arc is drawn along the internal diameter of the thread, approximately equal to * 1 2 3/4 circles, open anywhere (Fig. 1,2);
b) in the hole - with solid main lines along the internal diameter of the thread and solid thin lines - along the outer diameter.
On sections parallel to the axis of the hole, a continuous thin line along the outer diameter of the thread is drawn along the entire length of the thread without running, and on images obtained by projection onto a plane perpendicular to the axis of the hole, an arc approximately equal to 3/4 of the circle is drawn along the outer diameter of the thread, open anywhere (Fig. 3,4).

When depicting a thread, a solid thin line is applied at a distance of at least 0.8 mm from the main line and no more than the thread pitch.
3. The thread, shown as invisible, is depicted with dashed lines of the same thickness along the outer and inner diameters (Fig. 5).
4. A line defining the thread boundary is drawn on the rod and in the threaded hole at the end of the full thread profile (before the start
escape). The thread boundary is drawn to the line of the outer diameter of the thread and is depicted as a solid main or dashed line if the thread is depicted as invisible (Fig. 6-8).

5. Hatching in sections and sections is carried out to the line of the outer diameter of the thread on the rods and to the line of the internal diameter in the hole, i.e. in both cases to a solid main line (see drawings 3, 4, 7, 8).
6. The length of the thread with a full profile (without run-out) on the rod and in the hole is indicated as shown in Fig. 9a and 10a.
The thread length (with run-out) is indicated as shown in Fig. 96 and 10b.
If it is necessary to indicate the amount of run-off on the rod, the dimensions are applied as shown in Fig. 9th century
The run of the thread is depicted as a solid thin straight line, as shown in Fig. 9b, c and 106.
An undercut of a thread made all the way is depicted as shown in Fig. Pies in. It is allowed to depict an undercut of the thread, as shown in Fig. 1\b and d.
7. The main plane of the conical thread on the rod, if necessary, is indicated by a thin solid line, as shown in Fig. 12.
8. In drawings in which threads are not made, the end of a blind threaded hole may be depicted as shown in Fig. 13 and 14, even if there is a difference between the depth of the thread hole and the length of the thread.
9. Chamfers on a threaded rod and in a threaded hole that do not have a special structural purpose are not shown in projection onto a plane perpendicular to the axis of the rod or hole (Fig. 15-17). A solid thin line of the thread image on the rod should intersect the chamfer boundary line (see Fig. 15).
10. A thread with a non-standard profile is shown in one of the ways shown in Fig. 18, with all necessary dimensions and maximum deviations. In addition to the dimensions and maximum deviations of the thread, the drawing indicates additional data on the number of starts, the left direction of the thread, etc. with the addition of the word "Carving".
11. On the sections of a threaded connection in the image on a plane parallel to its axis, only the part of the thread that is not covered by the thread of the rod is shown in the hole (Fig. 19, 20).
12. Thread designations indicate, according to the relevant standards, the dimensions and maximum deviations of the threads and relate them for all threads, except conical and cylindrical pipe threads, to the outer diameter, as shown in Fig. 21, 22.
Designations for conical threads and cylindrical pipe threads are applied as shown in Fig. 23.
Note. The “*” sign marks the location where the thread designation is applied.
