Perfect fit for CNC
Bought the 5mm to 8mm converter. Fits tightly and holds torque well without slipping. Anodizing looks nice too.

High torque holding
Using this on a high-load application. No signs of wear after a week of continuous running. Very satisfied.

Good quality
The coupling itself is solid. Machining is precise. Took a bit longer to arrive than expected but worth the wait.

Works well for steppers
Used it to connect a NEMA 17 to a lead screw. Holds position well. Wish it came with Loctite though.
Q: What size hex key is needed?
A: Typically a 2mm or 2.5mm hex key depending on the specific shaft size ordered.
Q: Is the material stainless steel?
A: No, it is made from high-strength Aluminum Alloy 7075 for weight reduction and strength.
Q: Can I return if wrong size?
A: Yes, returns are accepted within 30 days if the item is unused and in original packaging.
Q: Can this handle high RPM?
A: It is balanced for general use, but we recommend staying under 3000 RPM for optimal longevity.
Q: Does this work with NEMA 23 motors?
A: Yes, provided the shaft diameter matches the selected size option.
