The present invention provides a spray arm assembly comprised of a tubular member rotatable about a fixed axis. The tubular member has an internal passage and a central axis extending a length of the tubular member. A nozzle assembly is attachable to an end of the tubular member and fluidly communicates with the internal passage of the tubular member. The nozzle assembly is comprised of an insert attachable to the tubular member in a predetermined position. A nozzle body has an aperture therein defining a spray orifice. The nozzle body is mountable to the insert in one of a plurality of positions wherein the spray orifice has an orientation based upon a position of the nozzle body relative to the insert. A fastening means is provided for fastening the insert and the nozzle body together in one of the plurality of positions.
