A method for manufacturing a prechamber spark plug including an external thread and a cap including at least one through-opening. The method includes: providing the prechamber spark plug without a cap and including a cylindrical circumferential surface for the external thread. Mounting the cap, which includes at least one through-opening, in an arbitrary alignment at the prechamber spark plug, and creating the external thread at the circumferential surface in such a way that a thread start and/or a thread end of the external thread is aligned in relation to the through-opening at a predetermined position.
