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

I bought 2 sets of these about a week apart, a 5mm and then a 7mm. They are well made, and seem to be the correct size, assuming my 5mm shafts are exact also. However, oddly, both sets came in a little ziplock back, but if you open the ziplock the bag is still sealed and must be cut. Also, be aware that the tiny set screws hide perfectly in the flange holes, so dont lose them.

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

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

Fast service, quality product

Good quality material and built as it should be. Worked as needed.

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.

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

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.

good quality

It is a perfect little coupler.
