- Premium Brass Material for Durability: The heat-set threaded inserts for 3D printing are made of quality brass, extremely sturdy, not easy to break or deform, so each insert nut can be used for a long time and is easy to use. Also can withstand high temperatures above 300°C / 572°F. Excellent thermal conductivity also makes your 3D printer work more effectively.
- 5 Sizes in Bulk (M2–M6, 300pcs):A super-sized kit covers diverse needs with M2/M3/M4/M5/M6 inserts. Each size is clearly labeled in compartments for easy storage and quick access. Corrosion-resistant brass allows reuse after removal. Once cooled, inserts lock tightly into plastic parts, preventing loosening during operation.
