Read my post before making negative comments.
I didn't suggest using a set screw as a set screw. I suggested a way to turn a setscrew into to pin. The method that I described works very well if you don't have the tools to do a keyway.
If anyone remembers our double jointed arm from two years ago, each arm had a double sproket reduction and we attached all of the sprockets using the setscrew pinning method I described. We never had a problem and we had to carry up to 150 ft-lb of torque in the "shoulder" joint.
Just a point to note: just because it uses a setscrew as one of the parts, doesn't mean it is being used as a "traditional" set screw. The implementation is more important than the parts list.
