Well made and easy to use. They don't clamp to the shaft (other than the set screw) so measure carefully before buying. I needed to shim mine with aluminum foil.

They are very strong and well made however the tool and bolt head basically stripped out after tightened on one end. My bad for gorilla torqing it I guess as it stripped out trying to remove it for more fitting work. One thing I forgot to do and everyone should do is grease or oil the threads be for using as it will help to prevent what I did.

Not much to talk about it's a coupling, used it connect a nema 17 motor to a 8mm lead screw. Biggest concern was the screws quality and they seem fine and did not show any signs of stripping out while tightening them. Will likely buy more.

These couplings worked to connect my 3D printer components, and the setup was simple. However, under a bit of stress, one of them cracked. They might be okay for very light-duty projects, but if you anticipate any strain on the coupling, I'd look for a sturdier option.

Really like how nice these are made with a great fit and finish. They work exactly as they should and serve the purpose. Come well packed. Not complaints.Good couplers, good price, would recommend.
