  • Package includes: 100Pcs M3Sx4.0 Threaded Inserts.
  • Perfect fit for your 3D printed parts: Use our threaded inserts to seamlessly retrofit your 3D printed components, easily embedding into blind or through holes using heat or ultrasound. It is the best solution for adding threads to 3D printing.
  • Stable and long-lasting: The threaded inserts are made of high-quality brass, ensuring optimal corrosion resistance and thermal conductivity. This means that each insert nut can be used for a long time and is easy to use. When the insert nut is no longer needed, just carefully remove it from the pressure part and the insert nut can be reused.
  • Secure fixation: The opposite spiral knurled nuts provide balanced high-tightening torque to ensure a stable connection. Guiding and insertion have been greatly simplified.
  • Versatile compatibility: Including PLA, PETG, ABS, PPS, PP, etc., the threaded sleeve will be securely fixed once the plastic of the parts surrounding the brass sleeve cools and hardens.
