Yes, most M6 nozzle may fit.
But in our experience they are flawed by numerous manufacturing mistakes including:
– Holes not sufficiently round
– Inside surface not correct due to use of wrong tool causing filament stick and carbonization
– Length not uniform causing head crash (could break glass plate and misaligning the head assembly)
– Top surface wrong geometry and finish causing leaks
– .. and more!
We do not recommend a 1 dollar nozzles on a 2.000+ € printer.
One crashed print and it is already not worth it.
We recommend my own nozzles, those from Deltatower in Switzerland and those from E3D in the U.K.
