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

Description claims that they are heat treated steel. However they are easily drilled and produce a shaving consistent with the cast iron. Spark test also points on the cast iron. Shaft holes are not rimmed and not very accurate. Flange is OK for a non-critical application. I would not use them for a hi-RPM applications or for a powertrain.

Ive bought multiple sizes and all have been the same quality so Im posting the same review for all. Inside diameter fits the motor shaft very well and the face is perpendicular to the shaft. The small set screws and threaded holes they go into fit perfect. Even the hex wrench thats included is strong. The parts have no burrs or sharp edges.

Needed this flange for my generator throttle and shut down linkage so I could add a remote linear actuator . No more getting in and out of the engine room to start the generator :)

livraison rapide et convient parfaitement pour mon projet

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.

Exactly what I wanted, and it arrived two weeks early.

bricolage.

good quality

Le paquet est arriver avec seulement 2 flange et il manque les visses de blocage !

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.
