Listed here are some specialty machined aluminum .047" (1.19mm) ball rod ends I did for a 1/12 scale modern F1 project and have decided to make it a regular cataloged part number.

Supplied in this listing are 4 pcs of .020" (.5mm) stainless steal tubing 2 inches (50mm) long, 4 rod ends designed to fit inside the tubing, 4 jam nuts with .031" (.78mm) hex that are engineered to fit over the tubing, and 4 - .032" hex mounting bolts.

There is no specific application for this part so you will have to come up with your own use.
