A locking nut includes a nut top, a nut middle, and a slip section. The nut top includes an integrally-formed bushing. The nut middle includes a threaded central bore suitable for threaded engagement on a threaded installation bolt, as well as a plurality of ratchet gears on an outer surface where each gear has a respective first slip surface and a first drive surface. The slip section includes a plurality of cantilevered posts having a respective free end, wherein on each post are formed a respective second slip surface and a second drive surface. When the slip section is rotated in a tightening direction, the slip section and the nut middle rotate together until a torque threshold is reached, where the second slip surfaces override the first slip surfaces to limit the applied torque. The locking nut includes structure to produce sound when the torque threshold has been reached. |

1. An apparatus having a longitudinal axis associated therewith and configured to secure a threaded bolt to a toilet bowl, comprising:
a nut top including an aperture disposed along said axis and having an inclined surface on a first axial side and an outer wall axially-extending on a second axial side; a nut middle having a threaded through-bore extending along said axis that is configured to mesh with the threaded bolt, said nut middle including a plurality of circumferentially-arranged ratchet gears on an outer surface thereof, each of said ratchet gears including a respective first slip surface and a respective first drive surface; and a slip section having a cylindrical-shaped body with an opening in which a portion of said nut middle is disposed, said slip section including a plurality of axially-extending and circumferentially-arranged posts, each post having a respective free end disposed radially-inwardly of said outer wall of said nut top, each post having a respective second slip surface and a respective second drive surface, wherein in a first state, said first slip surfaces of said ratchet gears engage said second slip surfaces of said posts and said first drive surfaces of said ratchet gears engage said second drive surfaces of said posts, wherein in a second state when a first torque in a first rotational orientation applied to said slip section relative to said nut middle reaches a predetermined threshold, said second slip surfaces of said posts slide relative to, over and off of said first slip surfaces of said ratchet gears, wherein in a third state when a second torque in a second rotational orientation opposite of said first rotational orientation applied to said slip section relative to said nut middle, said second drive surfaces of said posts engage said first drive surfaces of said ratchet gears to rotate said nut middle. |
