My yftk clone came with 3 pins. 1 in ss and 2 in nylon (???).

You can probably get some post screws in fasttech that are the same size or could be cut to fit. If it leakes a bit using a small piece of teflon tape should fix it.

I'm talking about the centre pin (see the photo above posted by @desuede) not the nylon pins (screws). Few months after SvoeMesto released the Lite 2019 they also made new centre pin, 1.2mm in diameter, the one that comes with the atty is 1.8mm.
