About this item

  • [SIZE] - Thread Dia: M2; Pitch: 0.4mm; Overall Size: 3.5mm x 6mm / 0.14" x 0.24"(OD*L)
  • [MATERIAL] - Made of brass material, high hardness and durable. Provides good mechanical properties with increased corrosion and heat resistance
  • [FEATURE] - The embedding nut has a guide so there is no need for a counterbore or countersink. Smooth surface, firm and uniform, easy to install.
  • [ADVANTAGE] - Due to the embossing process on the outer diameter of the insert, it forms certain friction and bites force with the brass insert after forming, which can be fixed on the inside so that it will not fall off easily. Has a certain torsion and tension.
  • [APPLICATION] - Can be installed by ultrasonic or heat into the plastic matrix, or formed during the injection, widely used in 3D printing injection molding to achieve tight fixation.

5.0 out of 5 stars I really like this design.
Reviewed in the United States on April 30, 2024
Size: M3 x 8mm x 5mmVerified Purchase
The design of these inserts is slightly different than some others I have. It causes less “push out” with the smaller diameter lead edge. I’m glad I switch over to this style. Fantastic product. Will order again.

they don't twist out or pull out, so long as you don't over tighten them you can pull on it with 100 lbs

5.0 out of 5 stars Not quite 60 but still the best deal on amazon and they are just right for a voron build.
Reviewed in the United States on July 19, 2022
Size: M3 x 4mm x 5mmVerified Purchase
I'm not even going to knock a star off for miscounting (I received 58) because there are so many ripoffs on amazon for these inserts. People want like $20 for a pack of 100. Two packs of these is still 30% cheaper and you'll end up with more inserts.

I used them in a voron build and they work excellently.

Got these to use with my 3D prints. Work excellent. Just have to make sure they go in straight so the bold/screw with align up correctly into the nut.
