i can say after using close to 20 of them the threads have been fine on all with no burs.

Works great for Prusa parts.

Shape of nuts are not uniform. Thread hole varies around from center.Was using these with maker-beam XL. Some nuts would fit in down through the slots of the beam, to install. Other's had to be filed in which to fit. Not an extreme big deal. They worked for my project just ok. Will probably look for a better product on the next project.

Found a few missing their screw threads, otherwise they are fine

They are impressively bad, very few, if any are actual squares, most of them are rhombuses. Also essentially none of the holes are centered, there might be 10 out of 100 that are actually usable, but that is just dumb luck. The threads seem acceptable, although they don't have lead in chamfers so starting the screws could be easier. They also do not exceed a 5.5x5.5x2.0 overall footprint, but keep in mind that the holes are not centered if you are working with tight tolerances.

These are no good for Prusa 3D printed parts, they are far too thick. Listing indicates thickness should be 2mm, actual thickness is 2.26mm. The square nuts that come from Prusa are 1.75mm.

I bought these (along with some bolts from a different seller) to put together my 3D printed Halo DMR, and they worked perfect, with no sign of stripping even though I screwed the bolts pretty tight. I included a picture of the full prop.
