All the terminations in this article were made with the GC Electronics 12-464 D-Sub crimp tool.
The proof is always in how they perform. To test these two terminals I held the ring end with one pair of pliers and the wire end with another set of pliers. I then pulled. In both cases the wire failed right in the middle. The crimp held perfectly which is exactly what you want with these small terminals and wires.
Good luck with your project!
