8mm shaft - perfect fit - thread tolerances are good.

livraison rapide et convient parfaitement pour mon projet

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!!!!

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.

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.

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.
