Can't handle moderate torque

These couplings are very weak to torque. I sheared 2 of them on my z axis within 2 days of use.

Good price and works well

I both currently use these and keep extras on hand. Occasionally my CNC mill will break one, but it's rare. I like this type because the will break before damaging my machine.
