All 30 nozzles were as close to 0.4 as I could confirm (using a cleaning needle measured to 0.39 with a micrometer). They are much closer to OEM nozzles as they have a bulkier piece of brass on the end of the nozzle making them much easier to grip with a wrench. The pictures show the AJSPOW injectors on the left and my first exchange kit from another seller on the right. My first replacement set was too small, I had to try to drill them out with a needle that didn't work very well. The finish might have been a little better, but never mind if they print like crap. Such a relief to be able to print well again after installation. The old nozzles also kept sticking, I'm not sure if it was a nozzle problem or something else. I will update the review of these nozzles to resolve this issue.
