Will this kit fit a hakko fx-888d soldering iron with the t18 series tip style?

I don't think so. I believe these are the 900 series tips. Some Hakko use them. I'm using a Yihua 939D and it calls for 900s. They fit and work well

Is the inner diameter really 3.5mm? Because the 900M and some of the other irons listed require a tip with a 4.0mm inner diameter.

Who knows? Chinese tips can be quite a bit off tolerances, which is one reason you are better off buying Hakko or Weller tips.

Will these fit a yihua 939d+-iii evo? the station comes with a yihua k917d iron and i've only found that internal diameter 5mm tips fit.

They are "900" series tips, so yes. However, don't buy those tips, or any Chinese knock offs. They are poor quality, maintain their heat poorly, and require a lot more heat to function normally. Buy some Hakko or Weller tips.

Great Value, works perfectly well form my soldering iron

I have a standard soldering iron, and these tips work well despite their cheap cost. Overall they heat high enough to melt solder, but I do not use all the tips. In the future I would purchase a smaller package with fewer tips since I do not use all of them

A great set!

Great tips, extremely durable so far and of man the choices. It has a tip or two for every job/ tight spot. Amazed by the value. I do think I will end up replacing them more often but at the price point that's just fine in my books!
