A torque plate for use with a sprinkler head in a fire suppression system is disclosed. The torque plate has a base from which one or more fingers project transversely. The torque plate is mounted on the sprinkler head. A protective cover surrounds the sprinkler head. The fingers project outwardly beyond the cover, allowing a tool to engage them. The tool is formed from an elongated body having a cavity that is sized to receive the cover. One end of the body interfaces with a wrench, the other end has one or more axially extending slots sized to receive the fingers of the torque plate. The sprinkler plate has a threaded nipple that engages a threaded fitting on the sprinkler system. Torque is applied to engage the nipple with the fitting by engaging the slots of the tool with the fingers and turning the tool with the wrench.
