Abstract: 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.
