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

Fast service, quality product

These are nice and easy to install. The material holds up well enough. They require a very predictable application, though. I made a tin can bot (The Ravioli-Poli) and used these to fasten the wheels. The jarring and pulling from turning loosened the set screw until both were loose and a wheel fell off. It wasnt stripped tho, hence the positive review. Just consider your application.

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.

Product as expected. Machined well. Only issue was that vendor included a 2mm wrench, but the Allen screws are made for a 1.5mm wrench. Set screws are small and some were found in the flange holes. Open carefully.

Working good

Me gusto los tiempos y el producto es de excelente calidad.

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.

The product is good (8mm flange) but the package is too fragile, arrived broken (the packing bag) and the lock screws were missing, they probably fell off the box because they were not screwed to the flange and since they are very small they fit between the box gap.

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

I needed a way to mate a small 5V motor to a ROKR Marble Run puzzle. These coupling flanges fit the 3.5mm shaft of the motor and offered a simple way to attach itself to the crank. They came with two set screws for each of the four flanges, although one was missing. That didnt matter, because I didnt need them all anyway. I have three unused flanges if anyone needs one.
