About this item

  • M3 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 or Prusa. With the help of heat from a soldering iron or ultrasonic, the insert nuts are simply embedded in a blind- or through hole
  • FIXED HOLD WITH EASY APPLICATION: Thanks to the geometry of the threaded sleeve, the threaded sleeve holds it firmly in the pressure part. The opposing spiral-shaped knurled nuts ensure a balanced high tightening and loosening torque, as well as a high tightening force. The guide has made insertion much easier
  • 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 SET: The ruthex thread insert set are lead free RX-M3x5,7 consists of 100 insert nuts with M3 internal thread and a length of 5.7 mm. The threaded sleeves can be inserted by ultrasonic and heat embedding

These work very well for your 3d prints. Easy to install even without an insert tip on your soldering iron. I just used a regular tip.

I am working on an EVA3 tool head for a Zero G Mercury 1.1 conversion and got these since they were the correct size from the bill of materials. They came neatly packaged in a bag and work as expected. They were easy to install with a heated soldering iron to push them in. The grip seems strong and the M3 screws thread perfectly through the inserts. Extremely happy with these and looking forward to using them to secure more prints and help me finish my conversion!

These are a great simple fix for that stripped-out tiny plastic screw. Just heat and press into the plastic and use a 2mm machine screw, and they're good to go. I've used them so far on a drone.

I've been using these for a while in my 3D printing projects for functional parts. They work great, look great, and are very easy to use with the Ruthex soldering iron insert tips. Definitely a must have for anyone printing functional parts or printer modifications.

These were exactly what I needed for a 3d printed violin I made! They're made well and can hold a great amount of pressure! The chin rest and the neck (both grey pieces) are being held with these. My only real problem with the product is the fact that it didn't come with the solder tip needed to melt these in and I had to buy it separately. It seems like something so simple should be added with this.

I have used these in a few 3d prints and they worked great. Installation was easy and they really helped to make a clean and secure connection between multiple 3d printed parts. I have taken apart and put back together parts multiple times, and the inserts are just as secure as when I first installed them.

These work great. I used them in a part that I had to reprint so I wanted to reclaim the inserts and sawed into the plastic from 3 angles and still had to pry them out
