This needle simply threads into the Hi-Speed Needle valve assembly
There is also a set screw pre-installed into the knurled part of the
needle, and a hole at the end of the needle so a piece of wire
or hex wrench can be used as a needle valve extension. The set
screw requires a 1.5mm hex wrench to tighten it.
