a dispensing nozzle extending from the second end of the housing, the dispensing nozzle including a conical member having an external surface and extending from the second end of the housing and a cylindrical member having a circumferential surface and extending from the conical member, the cylindrical member terminating in a closed end; and the dispensing nozzle having at least one dispensing passage that extends along a continuous length of the conical member and through the external surface of the conical member, to the cylindrical member, and along a length of the cylindrical member and through the circumferential surface of the cylindrical member. ### Claim 2 (depends on 1) The application tip of claim 1, wherein the housing has threads that are positioned proximate the first end of the housing that are configured to threadably attach the housing to a sealant source. ### Claim 3 (depends on 1) The application tip of claim 1, wherein the housing includes at least one projection member extending from an outer surface of the housing to aid in gripping the application tip. ### Claim 4 (depends on 1) The application tip of claim 1, wherein the at least one dispensing passage is a slot. ### Claim 5 (depends on 1) The application tip of claim 1, wherein the at least one dispensing passage is at least two evenly spaced openings. ### Claim 6 (depends on 1) The application tip of claim 1, wherein the conical member has a diameter that narrows as the conical member extends from the second end of the housing. ### Claim 7 (depends on 1) The application tip of claim 1, wherein the at least one dispensing passage is four evenly spaced openings. ### Claim 8 An application tip, comprising: a body having a first end, a second end and an internal passage, the first end configured to be selectively coupled to a sealant cartridge to receive sealant in the internal passage; and a dispensing nozzle extending from the second end of the body, the dispensing nozzle comprising: a conical member having a first end, a second end, and an outer surface extending between the first end and the second end, the first end of the conical member extending from the second end of the body, the conical member having a diameter that narrows as the conical member extends from the body; and a cylindrical member having an outer surface and extending from the second end of the conical member, the cylindrical member terminating in a closed end, the dispensing nozzle having at least one dispensing passage that extends a length of the dispensing nozzle comprising a first length extending along the narrowing diameter of the conical member and through the outer surface of the conical member and a second length extending along the cylindrical member and through the outer surface of the cylindrical member, the at least one dispensing passage configured to dispense sealant from the internal passage. ### Claim 9 (depends on 8) The application tip of claim 8, further comprising the body having connecting threads positioned proximate the first end of the body to threadably connect the application tip to the sealant cartridge. ### Claim 10 (depends on 8) The application tip of claim 8, further comprising the body including at least one projection member extending from an outer surface of the body to aid in gripping the application tip. ### Claim 11 (depends on 8) The application tip of claim 8, wherein the at least one dispensing passage is at least two evenly spaced dispensing passages. ### Claim 12 (depends on 8) The application tip of claim 8, wherein the at least one dispensing passage is four evenly spaced dispensing passages. ### Claim 13 (depends on 8) The application tip of claim 8, wherein the at least one dispensing passage is a slot. ### Claim 14 (depends on 8) The application tip of claim 8, wherein the application tip has a length of 1 to 3 inches long. ### Claim 15 (depends on 8) The application tip of claim 8, wherein the dispensing nozzle has an outer diameter of 0.3 to about 0.9 inch. ### Claim 16 (depends on 1) A method of using an application tip, the method comprising: inserting the dispensing nozzle of the application tip of claim 1 in a bore of a structure; activating a fluid cartridge that is in fluid communication with the application tip; rotating the dispensing nozzle within the bore to evenly dispense the fluid within a bore portion of the bore and a countersunk portion of the bore; and removing the dispensing nozzle from the bore. ### Claim 17 (depends on 16) The method of claim 16, wherein rotating the dispensing nozzle within the bore further comprises rotating the dispensing nozzle one quarter tum within the bore. ### Claim 18 (depends on 16) The method of claim 16, further comprising connecting the application tip to the fluid cartridge. ### Claim 19 (depends on 16) The method of claim 16, further comprising after removing the dispensing nozzle from the bore, inserting a fastener within the bore. ### Claim 20 An application tip, comprising: a housing having a proximal end, a distal end, and an internal passageway extending between the proximal end and the distal end, the proximal end of the housing having an opening to the internal passageway and configured to be coupled to a cartridge to receive fluid from the cartridge in the internal passageway; and a dispensing nozzle extending from the distal end of the housing and having a closed distal end, the dispensing nozzle comprising: a conical portion having a proximal end extending from the distal end of the housing and a distal end; an extension portion extending from the distal end of the conical member to the closed distal end of the dispensing nozzle; and a plurality of slots in a lateral sidewall of the dispensing nozzle in communication with the internal passageway of the housing, each of the plurality of slots extending along the conical portion and the extension portion of the dispensing nozzle and through an external surface of the conical portion and an external surface of the extension portion between the closed distal end of the dispensing nozzle and the distal end of the housing.
