I don't believe the dimensions are right

3/5

The flange has "M3" holes but they will not accept M3 threads. It is not possible to tap them. Maybe the right size would be ideal A little over 2 and a little under 3. These holes are 5mm and 3mm in diameter They could be tapped yourself if you had the time. A drill bit capable of drilling a full 3mm seemed not to give me any problems. It turned out, however, that the hole pattern was a bit out of square when I tried to mount it! It was closer to 15 than 14. There is an overall difference of 7mm over a 16mm pattern. There were four options and I think I found one that will do for assembling the prototype, but we would have to source this part somewhere else if a kit was to be developed. Despite the fact that they tapped the holes along the 5mm shaft, the set screws still needed tightening. The fit is a bit loose, but they should still I see no problems with the set screws or grub screws. It is even possible to make sure the key can enter them by grinding the included hex key a little. It has a lot of burrs, but I could have seen that in the product photo and was expecting to remove them.

The price was excellent for the product

4/5

I was hoping to find flanged shaft collars for a 3/8 inch shaft, but without finding them at a reasonable price, I decided to purchase these and simply increase the bore size from 8 millimeters to 3/8 inches. I was able to do it on my drill press with no trouble. On the flanges, I increased the size of the mounting screw holes as well. My five minute project took the time it took to modify all four items in the specifications I required. When other sellers charge this much or more for just one piece, in our opinion, it's hard to go wrong with this set of 4.
