Abstract
An anode cap assembly comprising a stamped metal cap having a generally cylindrical inner section and a closed outer section. An anode rod formed of a metal electronegative to steel is disposed in the cylindrical inner section and the steel core wire of the anode projects outwardly of the anode rod and is electrically connected to the outer section of the cap. The outer section of the cap preferably has a smaller cross sectional area than the inner section and is formed with a plurality of external flat surfaces to receive a wrench or tool. After assembly of the anode rod to the cap, threads can be rolled in the outer surface of the outer section of the cap so that the cap can be threaded to a spud welded to the outer surface of a tank.
