Brass Heat Set Inserts

Brass Heat Set Inserts are precision-engineered threaded nuts designed to be embedded into plastic materials using heat, creating durable and reusable threaded connections. These inserts are essential for reinforcing 3D printed parts, electronics casings, and mechanical assemblies where repeated screwing and unscrewing is required. Made from high-grade brass, they offer excellent thermal conductivity for easy installation and superior corrosion resistance. The knurled outer surface ensures a secure grip within the plastic substrate, preventing rotation or pull-out under stress. Commonly used in robotics, drone frames, consumer electronics, and prototyping, these inserts eliminate the need for nuts and bolts in confined spaces. Choosing our inserts ensures reliable, professional-grade assembly quality with a simple installation process using a standard soldering iron or heat press.
