Abstract: An offset line socket is presented which provides a tool for removing and installing line-nuts in close mechanical tolerance situations. The offset line socket is made up of a drive gear which is driven by a standard ratchet wrench. The drive gear is connected to two transfer gears which in turn drive the application gear. The application gear has an opening in it which is sufficient to allow the offset line socket to be placed over the pipe to be loosened or tightend. The hexagonal inner configuration of the application gear then attaches to the hexagonal line-nut. Once in place, a ratchet wrench drives the drive gear which in turn drives the application gear and removes or installs the hexagonal nut. The offset line socket is used in places where a standard wrench shaft would not turn because of mechanical obstructions. An alternate pivoting arm is also available for the socket which entirely closes the pipe access opening in the application gear for greater mechanical stability.
