The invention relates to the field of buildings, in particular to elements and parts of fasteners. The self-centering sealing insert in Figure 1a and Figure 1b has a central hole (position 1.1) penetrating through the interior of the self-centering sealing insert for a fastener to pass through. The main body is manufactured in the form of two identical combined truncated cones (position 1.2 and position 1.3), the large bases of which are located at the center of the main body and which taper towards the edge forming the central hole; the truncated cone is a part of a right cone formed by rotating a rectangular trapezoid around the side edge of the trapezoid, and the height perpendicular to the bottom edge of the trapezoid is H; the radius R1.2 of the large base is larger than the radius R1.1 of the small base, and the radius R1.2 of the large base and the radius R1.1 of the small base refer to the height of the side edge of the rectangular trapezoid.
