Abstract

A seal for an opening of a bore in a component, with a threaded screw, around a core shaft of which a helical screw thread is arranged. The screw engages in the bore and the thread creates a mating thread in a wall of the bore. The diameter of the bore is larger than the diameter of the core shaft. A helical channel, which is located between the core shaft of the screw and a wall of the bore, and which is delimited by the thread, is interrupted at a minimum of one point in a liquid-tight and/or gas-tight manner.
