Well sorted. Appears to be of good quality.

Actually correctly sorted. I have bought many of these kits and all the parts are mixed together. Nice to see that everything is sorted well. 5 Stars.

Pros
  • Best
Cons
  • Without automatic

Works best with nut inserts

Works great. I would buy it again but maybe try a different brand. You can buy stronger inserts, or you can buy inserts that are easier to install. I also found that most parts work great if you screw the screw directly into your prints.

Pros
  • Excellent design
Cons
  • New competition has arrived

Works well in various conditions

I bought these for use in wood but ended up using them in 3D printed objects. They work very well with 3D printed items, but not as well with softwoods like pine. I had to pull a few out of the tree.

Pros
  • Sturdy construction
Cons
  • No performance

Revainrating 5 out of 5

Exactly as described, hence 5*. However, this is a poor option for 3D printing or thermal pasting.

These nuts are molded for injection molding. They work, so to speak, for 3D printing or other heating applications, but they cannot take much load. Inexpensive and good range for simple work. But I buy nuts specifically for heating, the sizes we usually use.

Pros
  • Easy to read control panel
Cons
  • Reliability

Revainrating 3 out of 5

It pulls out easier than other designs.

I don't understand why the knurling is parallel to the direction of insertion. All other knurled brass inserts I have are angled to provide strength against pull. They all pull out with half the force of my other "same size" brass inserts. who knows if they serve some other purpose that I don't know about. but for my use of "tightening the screws in them" they just pull out too easily. I have ordered a different type but would like to find a use for it.

Pros
  • A sea of positive emotions
Cons
  • Good, but not very good

Fits well, works well

I 3D print a lot of parts including plastic cases for projects. Relying on a screw holding when driven into plastic is suboptimal. These knurled brass nuts solve the problem excellently. To use, put the nut in a suitable hole in the model, slightly smaller than the nut. Take a heated soldering iron and insert the soldering iron tip into the brass socket. Let it heat until the plastic starts to melt. Insert the nut and then remove the soldering iron. The plastic will harden and hold the nut in…

Pros
  • Impressive
Cons
  • Boring packaging
