Brass Threaded Heat Insert M2

These M2 Brass Threaded Heat Set Inserts are essential components for hobbyists, makers, and 3D printing enthusiasts who want strong, reusable threaded connections in 3D printed parts. Designed to be melted into plastic using a soldering iron, these brass inserts create durable, wear-resistant threads that allow for repeated screw insertion and removal without damaging the surrounding material.

Made from high-quality brass, these inserts feature a knurled exterior surface that grips firmly into the plastic once installed, preventing pull-out and rotation even under repeated use. With an outer diameter of 3.2mm, they’re compatible with standard 3D printed holes designed for M2 heat-set inserts, and are available in multiple lengths to suit different part thicknesses and mounting depths.

Whether you’re assembling enclosures, mounting electronics, or building functional prototypes, these heat set inserts provide a professional, durable fastening solution far superior to printing threads directly into plastic. A must-have addition to any 3D printing or maker workshop.
