Inserts M3S (100 pieces), M3Sx4,0 – Ruthex

ruthex M3 brass threaded inserts for 3D-printed parts

Ensure strong and repeatable threaded connections in your 3D parts.
The ruthex inserts are easily installed by heating with a soldering iron or ultrasonic and are pressed into blind or through holes.
After cooling, the plastic fixes the insert permanently.

Advantages
