Not a very advanced product so not much to say honestly but they work really well for 3D printed parts and is way better than the cheaper type that has this entirely vertical pattern on them. These comes with essentially threads that digs into the plastic really well. But maybe the best part, they come with a 3D model. Honestly bit of a miss on their part to not market that because it's really convenient to get a perfectly scaled 3D model you can insert into assemblies in cad. It's such a great detail that just makes these nice to work with. Simple addition that should be standard.

I use these in every single 3D printed enclosure I design and they are perfect. Just finished off a bag of M3's and I've ordered some M4 and M5
