I hope they come up with some larger 5mm ones for bigger projects. They are VERY tough to find.
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’m using this on a Halloween prop that doesn’t require a lot of torque, and it’s working perfectly. :-)
Oh yeah, I wasn’t sure what length screws I needed until I assembled everything, so I bought the screws from the local hardware store as the screws are a common size.
