Review: High-Quality Heat Inserts - 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.
Review: Nice inserts. - I have used Ruthex before. No problems. The inserts hold very well in #D prints. Recommended. Thanks.

## Features

- M2 THREAD INSERTS FOR YOUR 3D PRINTED PARTS: The ruthex threaded nuts can be retrofitted by heat or ultrasounds into parts of 3D printers from e.g. Anycubic or Prusa. With the help of heat from a soldering iron or ultrasounds, the knurled insert nuts are simply embedded in a blind- or through hole
- FIRM HOLDING WITH EASY APPLICATION: The threaded insert nut holds firmly. The knurled nuts have spirals in opposing directions that ensure tightening and loosening torque, as well as a high tightening force. The insertion has been greatly simplified
- STABLE & LONG-LASTING THREAD INSERTS: The inserts with internal thread brass, which ensures optimum corrosion resistance and thermal conductivity. This means that each nut can be used for a long time and is easy to use. The reusability of the insert nut is also possible by carefully removing them from the pressure part when they are no longer needed
- SUITABLE FOR A VARIETY OF PLASTICS: The inserts are designed for all thermoplastics. For example, the knurled nuts hold in PLA, PETG, ABS, PPS, PP and many more. As soon as the plastic of the part around the brass sleeve cools and hardens, the female threaded sleeve is firmly anchored
- PRACTICAL THREAD INSERT SET: The ruthex threaded inserts set are lead free and RX-M2x4 consists of 70 insertable nuts with M2 internal thread and a length of 4 mm. The threaded sleeves can be inserted by ultrasonic and heat embedding
