Designed for Injection Molding
You can use a soldering iron to heat up threaded insert and then pressing it into the hole. The softened plastic will flow into the knurl pattern and then harden to form a firm bond with the insert.
High-quality Brass Material
The threaded insert has a smooth surface without burrs and is easy to install. Due to the high thermal conductivity of brass, it can be heated and inserted into plastic parts faster.
Easy to Carry Threaded Inserts Kit
With adequate quantity and suitable sizes, these M2, M3, M4, and M5 brass knurled thread insert nuts can be widely applied for laptop plastic housings, 3D printers, automotive, electrical injection molding, and more.

No complaints. Cap screws fit well, good tolerances.

I printed a heat press for them and they were great after all what could go wrong?

The only beef I have with these parts is one end should have a portion of the diameter chamfered and slightly less in diameter to aid in guiding in the hole when doing the heated insertion.

A 3D-Printing enthusiast's best friend when it comes to assembling complex prints. I recently printed parts for a 4-cylinder short block. The inserts greatly simplified the assembly process of the main bearing caps and the rod bearing caps.

It says these are for 3D printing, but this is actually not the right kind for 3D printing. I didn't know better when I bought them. These are more for injection molding.

Started 3d printing not too long ago and I found about these recently.Game changer. They do what they are advertised todo.Just make sure you have the right soldering tips.
