## 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

### ⭐⭐⭐⭐⭐ Easy to use

Great product. Works as intended. Easy to heat with a soldering iron. No special tip required, just a large cone tip.

### ⭐⭐⭐⭐⭐ This is the only brand to buy, consistently perfect. Never fail.
*by T***R on August 15, 2025*

Buy these, no matter what. You’ll regret buying from others, promise. I use thousands of these for my products for customers. They are essential to my business. I recently tried to buy another brand that was a little cheaper and it was a bad mistake. About half of them have damaged or defected threads, but you don’t know until after you try a screw in them. This has caused me many failed prints, a lot of money wasted. All because I tried to save a few bucks. I will never go to any other brand, this is literally the only one I trust. I don’t leave reviews, but after the nightmare with the other brand that starts with a U, I felt it was imperative I help out others. Don’t buy anything else.
