ruthex M2 Threaded Inserts - 70 Pieces RX-M2x4 Brass Heat Set Insert for Plastic Parts - Metric knurled Nuts - Insert by Heat into 3D Printing Components

Overall, I’m very happy with these heat inserts. They shipped quickly and arrived in good condition with no issues. In use, the machining appears to be high quality and the knurling is clean and consistent. Screws thread in smoothly without binding or cross-threading. I primarily use these for 3D printed parts and have not experienced any fitment or durability problems. They perform exactly as expected and I would recommend them to anyone installing threaded inserts in 3D prints.

I have used Ruthex before. No problems. The inserts hold very well in #D prints. Recommended. Thanks.

Went through the pack in a week. Very high quality and the specs on the front are exact especially for 3d prints. Great value and they fit great and are very strong. I used them for an outdoors application and they are showing no wear or movement.

I've never had any trouble setting these with my soldering iron. I don't use any additional tools, jigs, or presses. Pretty easy stuff They work well and don't come out. Big fan

These inexpensive brass inserts turn 3D printing from making whimsical toys to making REAL parts!! From industrial and electronics, to racecar parts. Just awesome.

These heat inserts fit perfectly into one of my 3d prints.

Quality inserts, but the case came with no latch to keep it closed, so It's pretty much useless.

Seems to work really well. Used on a small project and hod no issues.

Comparado con los productos más económicos, se ven de mayor calidad, de ahí el precio mayor. Me ha gustado mucho que el fabricante muestre tanto las medidas del inserto como el agujero donde se tienen que alojar además de los márgenes entre insertos o del inserto a un extremo de la pieza.
