Heat-Set Threaded Inserts, 607-Piece M2-M6 Lead-Free Brass Kit with Six Tips and Soldering Iron Adapter - FFVRVSS

Heat-set threaded inserts add durable reusable metal threads to 3D-printed and molded plastic parts. This FFVRVSS kit combines 600 lead-free brass inserts in M2, M2.5, M3, M4, M5 and M6 sizes with six matching heat-set tips and one soldering-iron adapter. Opposing 45-degree spiral knurling helps the insert resist torque and pullout, making the set useful for prototypes, electronics housings, toys, furniture and repair projects.

The brass is listed for temperatures above 300°C or 572°F and works with thermoplastics including PLA, PETG, ABS, TPU, PPS and PP. Organize sizes in the labeled case and verify the exact insert dimensions against your printed hole before heating. Press the insert straight with controlled heat and allow the plastic to cool without movement. Variant offerings differ in size, quantity and included tools, so confirm that the selected kit includes the tips and adapter.
