Excellent for Prototyping
These inserts work perfectly with my 3D printed parts. The knurling grips the plastic well without cracking the hole.

Easy to Install
Used a heated tip from a soldering station. They went in smooth and straight every time.
5 FAQ
Q: Is this material magnetic?
A: Brass is non-magnetic. These inserts will not interfere with magnetic sensors.
Q: Can I use glue to secure these instead of heat?
A: Not recommended. Heat insertion ensures the plastic flows into the knurls for maximum hold.
Q: Do you sell M10 size inserts?
A: Currently we stock up to M8. Please contact us for custom larger sizes.
Q: What hole size is recommended for M3 inserts?
A: Please refer to the specific datasheet for the M3 variant, as it depends on the plastic material used.
Q: What is the warranty period?
A: We offer a 1 year limited warranty against manufacturing defects.
