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

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

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.

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.

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

bricolage.

Made new extensions for long selector, volume and tone controls when plastic coupling broke. They work well

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

Needs to come with inserts between the flanges
