About this item

  • Package includes: These threaded insert combination kits are available in 10 sizes, including different sizes of M2, M2.5, M3, M4, M5, M6. Each specification has its own separate compartment in the plastic box, and we have attached labels with detailed annotations of key data for easy storage and finding.
  • 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.

They seem to be built well enough for brass inserts. The size was accurate and they work for the project that I was doing.

Holds stronger than I thought they would.

Very good and are easy to install with a soldering iron. Can be pressed in cold but an iron makes it so much easier

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.

I used these for several miscellaneous 3D printing projects. These inserts are super useful for 3D printing because you can melt them right into your model and add some nice clean threads wherever you need them. I've used several different brands now and these are some of the better ones I've tried. Its nice that the dimensions are provided very clearly in the listing and on the outside of the packaging.So far, I've installed a few dozen of these inserts and haven't had a single issue. All of them have clean threads and were the correct size. This particular size of M3x5.7 is the most common size I use and this brand lives up my expectations. 10/10

Presi per inserirli in pezzi stampati in 3D, nulla da segnalare, fanno quello che devono fare e resistono bene

Funcionan. Si tienes proyectos con este tipo de solución las recomiendo. Lleva varios tamaños tanto en ancho como en profundo. Las uso en madera. Taladro agujero algo más ancho, relleno con pasta de madera e inserto una rosca. Al secar queda embutida perfectamente en la madera.
