Product Details
✓#2-56 + #4-40 + #8-32 + #10-24 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-2-56x4 + 100 pieces RX-4-40x5.7 + 50 pieces RX-8-32x8.1 + 50 pieces RX-10-24x9.5 Insert nuts with #2-56, #4-40, #8-32 and #10-24 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
