I'm wondering if there is any pro's and con's with the female threaded hotend nozzle-- like on the M2-- versus the male threaded nozzles--like E3D, Hexagon etc?
I've also always wondered why nozzles don't use a tapered thread like BSPT or NPT. Is it not necessary for it to seal that well?
Male vs female threaded nozzles
Re: Male vs female threaded nozzles
One issue you'd have with tapered threads would be getting the height consistent from nozzle to nozzle. A straight thread that seats on a shoulder will be more consistent.
The M2 nozzle does not seal at the thread, but at the unthreaded face below the thread.

Re: Male vs female threaded nozzles
I would think that a female threaded nozzle like the M2 may be more forgiving since the liquid plastic would be traveling from a narrow volume to a wider volume. In a male threaded nozzle, the plastic would travel through the opposite scenario and push against the threshold between the nozzle and tube.
But in reality, I'm just being a keyboard engineer, there is likely no difference in performance between the two.The only problem is that there are two options and each manufacture makes their choice and sticks with it.
This is why standardization of industries is a good thing. Perhaps we should petition to the ISO to settle the dispute once and for all.
