Drawing on flight logs, yacht-docking records, photos from Rybka’s Instagram account, and other evidence, Navalny suggests that Prikhodkointo the female member through the screwing process. The free edge of one of the members (generally the male) called nose has an annular surface radially oriented, which is pressed against a corresponding surface of the other member (shoulder of torque). In these types of connections there may or may not exist another surface directed axially in the free extreme of one of the members that functions as a seal when pressing itself against a corresponding surface directed axially on the other member. The annular surfaces radially oriented remain compressed as a result of the assembly of the connection. The maximum torque that the connection is able to absorb is limited by the dimensions and design of the free extreme of the first member and of the shoulder
