Hydrospanner/Legends

The hydrospanner is a type of common hand tool used as an all-purpose socket wrench and bit driver. It is used to tighten or loosen types of fasteners such as: nuts, bolts, and multiple sizes of screws and pins. Hydrospanners of common throughout the Galaxy and are used in the building, repairing, and dismantling of any mechanical device or structure like droids, equipment, starships, and related systems of engineering.

Most common hydrospanners can create a large amount of torque with little effort on the user's part, and offer features for convenience. The Regallis Engineering FastTurn-3 Hydrospanner has an internal powersource with a tension adjuster and a hinge on the socket driver to alllow the user access bolts and such in tight angles. The FastTurn-3 also has a spare bit compartment in the handle and a data port to connect a diagnostic device or datapad. The Fasturn-3 can also fit different sized nuts ranging from 2mm to 250mm in diameter, while using a small fusioncutter to remove molecular adhesives or welds before loosening.

How it works
A hydospanner works by using a small yet powerful hydraulic compessor to turn a rotary driver which can be fitted with different types of standard bits. The driver is powerful enough to drive screws through duraplast and transparisteel. It can be powered either internally or externally.

Behind the scenes
The hydospanner is akin to real world power drills and socket wrenches. It is mentioned in the expanded universe yet is rarely, if ever, explained in what it does.
