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.

Well made and true to advertised dimenions
Great little shaft collars with flanges. Dimensions were accurate and surface finish is good. They worked so well I got a second set.

Inexpensive Metal flanges seem well made and come with screws and allen wrench
I needed a flange for mounting a plastic fan unit that came with a flimsy flange molded in, that had failed. I dremelled out the old flange and added one of these metal flanges attaching it with screws and glue Bonus It comes with an allen wrench of the right size for the tiny set screws supplied

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.

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.

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