Annular-shaped thin nut for use in e.g. pivot connector, has interior circumferential surface for carrying threaded net that extends around longitudinal axis and presents asymmetrical trapezoidal profile in cutting plane

摘要

The nut (18) has an interior circumferential surface (18B) for carrying a threaded net that helically extends around a longitudinal axis (X). The net presents an asymmetrical trapezoidal profile in a cutting plane that includes the longitudinal axis. The nut exhibits an interior radius that is defined by a distance between the longitudinal axis and the interior surface, where an external radius of the nut is defined by a distance between the longitudinal axis and an external circumferential surface (18A) such that the interior radius is equal to or 0.9 higher than the external radius.
