## Description

ruthex Threaded Inserts M2 + M3 + M4 + M5 Assortment Box - 70 + 100 + 50 + 50 Pieces - Brass Heat Set Insert for Plastic Parts - Metric knurled Nuts - Insert by Heat into 3D Printing Components

## Features

- M2 + M3 + M4 + M5 THREAD INSERTS FOR YOUR 3D PRINTED PARTS: The ruthex threaded nuts can be retrofitted by heat or ultrasound into parts of 3D printers from e.g. Anycubic, Creality or Prusa. With the help of heat from a soldering iron or ultrasound, the insert nuts are simply embedded in a blind or through hole
- FIRM HOLDING WITH EASY APPLICATION: Thanks to the geometry of the threaded sleeve, it holds firmly in the pressure part. The opposing spiral-shaped knurled nuts ensure a high balanced tightening and loosening torque, as well as a high tightening force. Through the guide, 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 insert 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 threaded sleeve is firmly anchored
- PRACTICAL THREAD INSERT BOX: The ruthex threaded inserts box are lead free and consists of 70 pieces RX-M2x4 + 100 pieces RX-M3x5.7 + 50 pieces RX-M4x8.1 + 50 pieces RX-M5x9.5 Insert nuts with M2, M3, M4 and M5 internal thread. The thread inserts are supplied in a practical assortment box. The threaded sleeves can be used by ultrasonic and be inserted by ultrasonic and heat embedding

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect spec for Voron 3D printers
  

*by N***. on Reviewed in the United States on October 25, 2024*

These inserts are high-quality and have provided no issue so far with the printed parts on my 2.4 that I am rebuilding. Definitely consider these threaded inserts over some of the generic, cheaper ones you find.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Lead Free & Cadmium Free!
  

*by D***W on Reviewed in the United States on November 19, 2024*

If you're making anything which might be sold in California, or you just don't want to use any parts or materials which contain Lead or Cadmium, these are an excellent choice. And for such a reasonable price, why would you want to use anything else? The quality is as close to perfect as anything you'll find, and Ruthex also makes an excellent set of insert tools which fit nicely into many of the currently available soldering irons. For these reasons, I've purchased these in a range of sizes along with the Ruthex insertion tools. I can't recommend these enough, and have a hard time understanding why any manufacturer of brass inserts is still using brass containing lead and cadmium. Sadly, I don't know of any U.S. insert manufacturers which use lead free/cadmium free brass. I've actually called them and asked. Hopefully next year, RFK Jr. can start changing this. And I hope he does, because I'd like to start buying my inserts from U.S. manufacturers.

    Work great and easy to set using soldering iron when inserting and the used epoxy to fix.
  

*by G***. on Reviewed in the United States on November 13, 2024*

Inserts were used to modify the base of the GenMachine PC to rotate the PC 90 degrees from the factory mounting screws to change the position of the connections from the top to the side to relieve stress on the connections and improve the appearance of the setup.I used JB weld for plastic to fix the inserts at the base.
