A Shipboard Multi-tool. The Multi-tool includes a pair of groups of tools that are individually-extendable from the handle in order to allow the Multi-tool to operate a plurality of different shipboard mechanisms with a single assembly. One group of extendable tools includes spanner and box wrenches. Another group of extendable tools includes key-type wrenches. The individual extendable wrenches are lockable in a variety of angular positions relative to the handle to provide the user with several configurations with which to use the wrenches. The locking mechanisms are operable by depressing a spring-loaded push-button.

A method and apparatus comprising a structure and a connector. The structure may have a number of walls forming a channel with a first opening and a second opening. The connector may be associated with the first opening. The connector may be configured to change a size of the first opening.

A tool for torquing a regulator onto a cylinder of a portable cylinder assembly. The tool includes a nut and a socket. The nut is configured to fit around a body of a regulator of a portable cylinder assembly. As such, the nut has a first set of grooves that avoids one or more valve assemblies on the body of the regulator. The socket has a cavity extending therethrough such that the cavity consists of three sections: a top section, a middle section and a bottom section. The top section of the socket is configured to be coupled to a device that applies a torque force on the socket. The middle section of the socket is configured to avoid a case of the regulator which is disposed above the body of the regulator. The bottom section of the socket is configured to be coupled to the nut.

The inventions relates to a tool 10 that is adapted to loosen or fasten connector nuts located in areas of reduced space. The tool 10 is particularly useful because it allows manipulating basin nuts 40 located between the lower portion of the basing and piping that provides water to the faucets that are attached to the basin via the nut. The tool comprising a body having a first section adapted to receive the fastening means and a second section adapted to receive the torque, the first section and the second section being adapted for attachment to each other to transfer the torque to the first section, wherein the first section is adapted to allow piping to be located adjacent the second section during use of the tool to allow the first section to receive the fastening means. The tool may be configured as a socket. The invention also relates to a kit including the sockets.
