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

good

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.

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.

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.

It is a perfect little coupler.
