The second nut to be fastened in the opposite direction so
that the nut is not loosened from its place. Because the normal nut will be
squeezed when turned to the opening direction, the name is
"contra".The hexagonal counter nut is called the hexagonal second nut
which is inserted in the opposite direction so that any of the nuts does not
come loose. Converts the normal end to the direction of opening and compresses
it. This prevents the first bolt from loosening and opening. Generally, it is
preferred that high vibrating machines do not come out of the nut due to
vibrations in industrial fields where they are used.
