Awsome !!! Fast , good parts 🙂

The storage case was a nice touch, and helps keeps the individual pieces seperated. My only two complaints are quality related. The black oxide coating (or whatever surface treatment they used) on the screws was very cheap/poorly applied and did not adhere very well to the base metal. Much of the "coating" rubbed off in my bare hands prior to use. If you're worried about rust, these may not be the best option for you in the long run.When it comes to the ease of use and overall functionality, the hex heads were slightly undersized. (Almost as if their broaching tool was excessively worn during production.) It wasn't a deal-breaker, but it was annoying. My brand new Bondus and Wera allen wrenches would not fit inside the hex unless I used the "ball" end of the wrench. (Yes I was using the correct sized wrench.) I'm sure if you were to use a cheapo Chinesium Allen wrench of dubious quality it would work better, but quality tools made to proper tolerances were too tight to be useful unless using the "ball" end - and even then the fit was snug. You could physically feel the ball end "snap" into place.For the money and speed of delivery, I can't complain too much. It's just a mildly annoying.

Used them to add some plexiglass panels to a sainsmart coreception 300.Just what I needed to get the job done.

I like this item because I use them to construct and assemble track for CNC

These nuts fit perfectly in my 2020 extruded aluminum. I'm working on a few projects, and needed a way to attach to 2020 without drilling into it. These fit in the slots perfectly and allowed me to fasten to the rails easily. They feel like they're decent material, I didn't notice any issues with cross-threading. Everything tightened down nicely without stripping out. This was exactly what I needed.

Doesn't fit standard 2020 rail (20x20mm) which has about 5.3mm wide slots, only fits 2020V which is closer to 6.3mm wide slots

These T-nuts are just what I was looking for and I didn't have any issues with quality. 100 is plenty for my 3D printer enclosure that I've been working on, and I have some spares for further projects.
