DIN 906 threaded plugs are used to close bore holes with cylindrical tapered internal thread.
The tightness depends on the medium, pressure, temperature and material pairing. The design with GPC thread coating provides a higher degree of safety.
The official DIN 906 standard sheet also provides for thread sizes M39x2; M52x1.5; M52x2; M56x2 and M60x2.
