Package includes: These combination threaded insert kits are available in 15 sizes, including various sizes of M2, M2.5, M3, M4, M5, and M6. Each specification has its own separate compartment in the plastic box, and we have included labels with detailed notes on key data so you can easily store and find them.

Perfect fit for your 3D printed parts: With our threaded inserts, you can easily upgrade your 3D printed parts. They can be easily inserted into blind or through holes using heat or ultrasound. This is the best solution for adding threads to 3D printers.

Stable and durable: 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 handle.

If the insert nut is no longer needed, it is simply and carefully removed from the printed part, and the insert nut can be reused. Secure fastening: Counter-rotating spiral knurled nuts ensure a stable connection thanks to uniformly high tightening torques. Guiding and insertion are significantly simplified. Versatile compatibility: Includes PLA, PETG, ABS, PPS, PP, etc. The threaded sleeve will be securely fastened once the plastic of the parts surrounding the brass sleeve has cooled and cured.
