I'm pretty sure that it is generally accepted that
threads/grooves/spikes/etc are not the solution. It is better to
maximize the surface area and generate uniform pressure over it. The
wrap-around clamp design by the guy who refurbishes prop pitch rotors is
a good example of that.

You could also bend your own from all-thread. I've bought it in the past from
my local big box store. I think, without any engineering data at all, the
having threads bearing on the mast would give a slightly better grip. Then

Good luck & 73.
