A quick installation hot melt adhesive dispensing nozzle assembly, for use in connection with hot melt adhesive dispensing modules, comprises a nut member which is adapted to threadedly engage a hot melt adhesive dispensing module seat member, and a hot melt adhesive dispensing nozzle member which is initially assembled together with the nut member. A plurality of orientation pins are adapted to effectively interconnect the nozzle member to the dispensing module seat member such that a particular angular orientation of the nozzle member, and therefore the angular orientation of the dispensing ports defined within the nozzle member, may be predeterminedly positioned with respect to the longitudinal axis of the hot melt adhesive dispensing module. The nut member is rotatable relative to the nozzle member such that the nut member can be threadedly engaged upon the hot melt adhesive dispensing module seat member while the angular orientation or disposition of the nozzle member is maintained at its predetermined position with respect to the longitudinal axis of the hot melt adhesive dispensing module as a result of the interconnection effectively defined between the nozzle member and the hot melt adhesive dispensing module seat member by means of the orientation pins. In this manner, only the nut member needs to be grasped either manually, or by means of a single tool, in order to achieve the fixed installation of the nozzle member upon the hot melt adhesive dispensing module.
