Doesn't clamp tight at all before stripping. There is only one clamping screw on each end, no set screws.

For a 3d printer or some other low torque application this would probably be ok. You can not tighten these enough to get a good clamp. The threads just strip right out. I ordered a package of three and broke the threads out with almost no force on two of them. I had a 6-32 tap so I was able to tap the threads a little bigger and that is holding for now but I don’t trust them for my application (CNC router). Save yourself some time and money and get yourself some higher quality ones.
