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

The bag arrived ripped open. Now the 4 flanges and the allen key were in the bag, but all 8 screws were missing from the bag. I need 8 screws to fit those 4 flages. I sure wish someone would contact me.

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.

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.

Fast service, quality product

good

Just tried to use my 6 mm shaft only to realize that its 5.9 mm and doesn’t fit. Super lame, if anything it should be 6.1mm , that’s what the set screws are for!!!!

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

Needs to come with inserts between the flanges

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.

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.
