4Pcs Flange Coupling Connector, Rigid Guide Model Coupler Accessory, Shaft Axis Fittings for DIY RC Model Motors (3mm)

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

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.

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.

... as described and great fit with my Polulu motors

Grate

Received the 4x couplings and an Allen key - But only one grub screw though and so not 5 stars. I hope I have some laying around...

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.

Niet wat ik verwacht had

Really good quality.
