Perfect Machining and Great Design – Each Flange Was Flawless
Perfect Machining and Great Design – Each Flange Was Flawless The manufacturer can be rightfully proud of the superior craftsmanship of the workers and high Quality Control inspections. Each flange was perfect: dimensions correct, NO dangerous sharp burrs left over from machining, chamfered guides for axle hole, chamfered beveled guide to screw threads for easier screw starting, and smooth screwing perfectly shaped internal threads. It was really polite, or something, that the manufacturer included the tiny Allen Wrench for the M3 socket head grub screws.

great item.
Would have given five stars, but once installed they were off just a bit had to flatten on lathe to run true. Well worth buying if not needing perfect true. Would buy again. Also would be nice if added at least two extra set screws.

Fine as long as your assembly does not have any vibration. Otherwise, the set screws loosen easily
I've used these for a number of applications. They're fine as long as vibration isn't an issue. If there's even a little bit of vibration in your assembly the set screws quickly loosen and render the piece useless. I'd happily pay a bit more for a piece that doesn't have this problem, but I can't find a better version.

Good quality, fast shipping.
Nice quality, used to attach to output 14m shaft of worm gear reducers (after removing key) etc.

Exactly as expected.
Fits the three 8mm rods that I needed them for. Threaded screw fits properly and snugly. I had a bit of a laugh in that the resealable package ("ziploc" style) was heat-sealed shut BELOW the reseal, so after breaking the heat-seal (cutting it off) you couldn't reseal it anymore.

Good product.
Would have given 5 stars if the Allen set screws were a bit longer. Longer screws would work better with "D" shafts on motors.
