Union nut with 4 grips for generic ball joint

When I had designed a generic ball joint (which I needed of a mobile phone holder in my car) I figured that it worked much better than I had thought. That got me interested and I developed this special union nut with 4 extra strong grips to see if that would lock the joint even better... and it did ;-)

The original ball joint was published on my main page at Printable if you are interested:
