They seem to have the right hole size unlike others I've bought. My 0.4mm acupuncture needles (which measure exactly 0.40mm on several calipers) fit nicely in the hole of these attachments (I have 2 of them). Needles get stuck in many of the other (25) plain brass nozzles I bought online and some of them had burrs that needed cleaning. Others work well, but I like the lack of flow regulation and the longer life that this one promises. We'll see about the durability.
