An adjustable wrench uses colors for identification. The adjustable wrench includes a bit including multiple identification zones and a pointer in addition to a body and a movable jaw. The body includes a stationary jaw extending from a front end. The movable jaw is movably connected to the front end of the body so that a distance between the jaws is adjustable. The identification zones are formed on a side of the body. Each of the identification zones is in a color corresponding to a size of a workpiece. The pointer is formed on a side of the movable jaw. The distance between the jaws is set to be a value corresponding to the size of the workpiece when the pointer is aligned with one of the identification zones.

The subject matter described in this specification relates generally to a tool for installing a flexible metal conduit screw-in connector onto a flexible metal conduit and a method for installing the flexible metal conduit connector tool. The flexible metal conduit screw-in connector tool includes a handle, a centering rod, and two studs. The flexible metal conduit connector tool is to engage a flexible metal conduit screw-in connector.

A grease fitting installation tool is disclosed. The grease fitting installation tool may include a hand tool useful for installing and uninstalling a grease fitting with a hexagonal collar, a threaded shank, and a nipple, i.e., a Zerk fitting. The hand tool may have a first tool head and a second tool head, each able to receive and manipulate a grease fitting. The first and second tool heads may be attached end to end, joining the heads in the center of a hand tool by a couple. The couple may have a wrench interface allowing the hand tool to be engaged by a wrench or other tool. Each tool head may include a hollow socket with a socket aperture and six internal contact surfaces that are hexagonally arranged. The tool head may also include a deformable, cylindrical gripping member disposed within the hollow socket for retaining the grease fitting when the grease fitting is inserted into the gripping member.

A tool for controlling a controlled element of a height adjustable foot of a furnishing item and the like includes an engagement portion and a handle coupled to the engagement portion and having two arms shaped to embrace an outer edge of the height-adjustable foot and keep the engagement portion associated laterally with the adjustable foot. The engagement portion is arranged between the two arms and includes a toothing with a toothed section that extends over a rounded area of the surface between the two arms of the handle so as to engage at least one toothing on the controlled element of the adjustable foot. The teeth of the toothed section and the teeth of the at least one toothing of the controlled element are asymmetrical and angled, enveloping, curved teeth that follow the circular shape of the controlled element.

A hook spanner has a spanner body having two opposite side surfaces, a handle segment, and a hooking segment formed on an end of the handle segment. The hooking segment has an abutting end surface located away from the handle segment and having an abutting end surface extending obliquely from one of the two opposite side surfaces of the spanner body to the other side surface. The hook spanner is adapted to turn a nut having multiple grooves arranged around the nut. Each groove has an inclined surface extending obliquely and inwardly from a peripheral surface of the nut. The abutting end surface is aligned with the inclined groove surface of one of the grooves of the nut to stably turn the nut.
