I had been under the impression that the Hex Boly Style (as opposed to the H connector style) was no longer made or available.
I recently ordered one from Amazon, and was pleased to find that it was in fact a Hex Bolt style. I am not sure if anyone else was under this impression, but now you know, if you are doing a replacement and really want the Hex Bolt stlyle with thumb screw, that option may be available to you.
