Ruthex RX Kasten

Assortment box for threaded inserts M2, M3, M4, and M5 for your 3D printed parts. The ruthex threaded nuts can be inserted into 3D printer parts afterwards using heat or ultrasound. The press-in nuts are easily embedded into a blind hole or through hole using heat from a soldering iron or ultrasound.

Secure hold with simple application. Thanks to the geometry of the threaded sleeve, it holds firmly in the printed part. The opposing spiral knurled nuts provide a balanced high tightening and loosening torque as well as high clamping force. The guide has significantly simplified the insertion process.

Stable and durable screw threads. The inserts with internal threads are made from high-quality brass, ensuring optimal corrosion resistance and thermal conductivity. This means that each press-in nut can be used for a long time and is easy to handle. The reusability of the screw threads is also possible by carefully removing them from the printed part when they are no longer needed.

Suitable for various plastics. The inserts are designed for all thermoplastics. The knurled nuts hold in PLA, PETG, ABS, PPS, PP, and many more. Once the plastic of the part cools around the brass sleeve and hardens again, the internal threaded sleeve is firmly anchored.

Practical threaded insert set. The ruthex threaded insert box consists of 70 pieces RX-M2x4, 100 pieces RX-M3x5.7, 50 pieces RX-M4x8.1, and 50 pieces RX-M5x9.5 press-in nuts with M2, M3, M4, and M5 internal threads. The threaded inserts are delivered in a convenient assortment box. The threaded sleeves can be inserted using ultrasound and heat embedding.
