Quality item. Weldable.
NIce quality. I actually welded one of these couplers to a fender washer to make a replacement dryer knob that was no longer available.

Not for high torque applications
Not for high torque applications. I was planning on using this with a d shaft motor capable of producing more than 30kg-cm of torque. Unfortunately the set screw gets pushed out and strips the threads around 20kg-cm of torque. I tried a longer M3 screw and while better than the provided set screw it didn't work either. The single set screw per side is not a good design for higher torque applications. Other than that they seem great.

Inexpensive Metal flanges seem well made and come with screws and allen wrench
I needed a flange for mounting a plastic fan unit that came with a flimsy flange molded in, that had failed.I dremelled out the old flange and added one of these metal flanges attaching it with screws and glueBonus It comes with an allen wrench of the right size for the tiny set screws supplied
