## Customer Reviews

### ⭐⭐⭐⭐⭐ A very useful part for the CNC I am building
*by R***. on March 31, 2025*

Works perfectly to be able connect my Nema 34 motors to the ball screw which has a shaft of 10mm

### ⭐⭐⭐⭐ material choice will crack under long term use, steel would be better.
*by D***S on January 30, 2023*

aluminum fatigues in the long run, it is stiff, but not stiff like steel.

### ⭐ NOT TO SPEC
*by C***E on September 23, 2022*

These are oversized. The 14mm side is actually 15.44mm and once tightened down all the way it is 14.86mm. Doesn't even begin to grip a 14.0mm diameter shaft. Unfortunately the return window has passed so I'm stuck with them.
