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.

Screws fall out but nothing some Loctite can't fix!
They seem to work great if you add Loctite or super glue to the little screws, they tend to fall out. I think it is because the hole the screws screw into are a bit larger than it should be so it goes in loose. Without extra reinforcement the screw will fall out. The look well machined, seem to be durable, easy enough to install after you fix them up, good value for what I paid!

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.

Pretty good.
Pretty good product. Only complain is the little holes you attach whatever to it with, they are not threaded, and so tiny there finding nuts and bolts to attach something to it is a challenge. I just welded a 3/8 nut to the top of it and found that to work very good.
