4Pcs Flange Coupling Connector, Rigid Guide Model Coupler Accessory, Shaft Axis Fittings for DIY RC Model Motors (8mm)

Good quality and sturdy, they fit to the motor spindle and stay there. Comes supplied with grub screws and an tool for tightening them up

These adapters are perfect for attaching to small motors with 6mm spindles with two grub screws to secure them a nice solid fit

Good value for money. The only problem was that the very small grub screws came out during transit, and then came out of the plastic bag that contained the flags. Difficult to subsequently find.

Perfect Good quality product. very happy with them.

Good product, overpriced a little bit

I use these from an electric motor to a gear on my model fairground rides. Fit the motor axle nicely and are concentric. Holes for bolting through.

These were dead cheap so I can't really complain too much, but the internal measurement isn't quite 3mm - it's very slightly less meaning that a 3mm steel rod won't actually fit inside. Managed to fix this with a dremel and a bit of effort but not very helpful, so don't expect it to fit perfectly together immediately.

Good quality with grub screws to tighten onto a small drive shaft, I used these to attach a pulley wheel to a small 12v motor and they worked really well. not very big so check your sizing before you buy.

Es igual que lo descrito, los prisioneros allen cuestan de roscar al principio pero es normal, tambien es buen detalle que traiga dos prisioneros de sobra y su correspondiente llava allen.
