These ball joint ends are a very good fit on 2.0mm link rods. Good quality plastic, no too soft. They are long at 25.0mm overall, 18.45mm from BOTTOM of ball hole to end of link. As I mentioned they are a hard plastic, but not brittle. They can be cut to length with plenty of threaded portion left over. Uncut they will take ~15.0mm of threaded rod.RJX, noname .Alles bestens. Kann man kaufen.
