Save yourself some time
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.

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

Good fit
Good fit and sturdy.
