- 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.

Great product

### ⭐⭐⭐⭐⭐ excllent - I like the shape that allows easy insertion into the mounting hole
*by J***E on August 30, 2024*

I had not used these inserts before, but now, with my hobbies, I can't live without them. I used my 3D Doodle pen to heat them and push them in, and it worked great. These are packaged in a nice clear poly case and very well organized. Each compartment is built into the case. Both the outside and the inside of the lid show what is in each compartment. This is the right style to purchase. Each insert has an end that is smaller then the knurled part which makes it easy to set inside the pilot hole I drilled into the plastic. I had an old 3D doodle pen that I have not used for quite some time, and discovered that it is perfect to heating the insert and pushing it into the plastic. Nice little tab so I can hang it on the pegboard of my work bench.
