2.1. Form a toroidal area of the mounting hole between the diameter (point ) and diameter , is not regulated, but must provide:

— possibility of mounting plates with screws with a conical head with an angle from 40° to 60°;

— angle the theoretical cone at the point  — 65°;

— the minimum gap between the contact lines when fixing plates with screws with a conical head 40° and 60°.

2.2. Form the safety area of the mounting hole above the point is not regulated.

2.3. The position of the point is determined by the diameter and size due to the ratio .

3. Approximate weight plates provided in the application.

4. The notation of plates according to GOST 19042.

5. Technical requirements — GOST 19086.
