Upgrade your 3D-printed parts with reliable, long-lasting threads.
The 220-Piece Threaded Inserts Set from NOZL includes six popular metric sizes (M2 to M6), giving you the flexibility to work on a wide range of projects — from small electronic enclosures to mechanical assemblies.
Perfect for use with soldering irons or heat-set tools, these inserts melt smoothly into plastic, creating strong, reusable metal threads that won’t strip or loosen over time.
