Description: The universal aluminum mounting hub allows you to mount custom wheels and mechanisms to 5 mm motor shafts. The hubs are sold in pairs. The set includes one Allen wrench and two 4-40 set screws for securing the hubs to motor shafts.
Based on 2 ratings:
Everything came just fine in the package, and the included hex key for the grub screws was very well made. The hubs sit very tightly on D- or round shafts and seem to be quite sturdy. I wouldn’t hesitate to buy more if I needed them in the future.
I hope they come up with some larger 5mm ones for bigger projects. They are VERY tough to find.
