I ordered this item because I thought that it will fit T8 trapezoid lead screw, but it is intended for smaller diameter lead screw (6-7mm). Besides that little mistake on my side, part is of good quality.

These are not the pretties nuts for lead screws: they are dinged and scratched and very rough on the outside. However, they are machined just fine where it counts, and the threads work well on the lead screws, and they will likely continue to function as needed.

Nuts were not the good size. I made an error during my order. It's only my fault.
