A fuel-injection nozzle for an internal combustion engine is disclosed. The nozzle comprises a nozzle body ( 2 ), in which a nozzle needle ( 10 ) with a stop ( 34 ) is positioned so that it can be displaced, and a nozzle holder ( 6 ), in which a pressure pin ( 16 ) is displaceably mounted. A disc-shaped stop element ( 26 ) is provided in a zone between the nozzle body ( 2 ) and the nozzle holder ( 6 ). The nozzle body ( 2 ) and the nozzle holder ( 6 ) are axially braced against one another in such a way that the stop element ( 26 ) forms a first sealing surface ( 30 ), which lies adjacent to one section ( 23 ) of the nozzle holder and a second sealing surface ( 31 ), which lies adjacent to one section ( 24 ) of the nozzle body. Both the first and second sealing surfaces ( 30, 31 ) respectively have at least one cavity ( 36 ), which is punched, drilled and/or stamped.
