4Pcs 6mm Flange Coupling Connector, Rigid Guide Model Coupler Accessory, Shaft Axis Fittings for DIY RC Model Motors

livraison rapide et convient parfaitement pour mon projet

We used for coupling volume and switching rods found in high end amplifiers and receivers such as Kenwood & Yamaha. The original ones were nylon which eventually split. Nylon lasted 40+ years, maybe the metal will last as long.

8mm shaft - perfect fit - thread tolerances are good.

Was only given 4 out of 8 M4 fasteners, 3 of which were not in the bag. The bag was very difficult to open without cutting. Very small lip on the ID towards the base that would have to be removed to use them as a mid shaft through mount.

All 4 couplings were not 4mm. They were about 3.6-3.7 mm, which meant my 4mm shaft didnt fit. Probably defect if others got the right size.

6mm flange fits the motor shaft very well, and machining and surface finish are much better than what’s shown. I wouldn’t send it to space but your also shopping Amazon not McMaster. I have no complaints with what I received.

These flanges were great for rotating a small sensor that was coupled to the shaft of a stepper motor.

These are excellent! Fit and finish is perfect. Using these on 28BYJ-48 stepper motors. Great deal for the price.

It is a perfect little coupler.
