M3 Threaded Brass Insert

M3 Threaded Brass Insert

Create strong, durable threaded connections in your 3D printed parts with the M3 x 4mm x 4mm Brass Threaded Insert. Designed to be heat-set into thermoplastic materials, these inserts provide a secure metal thread that is far stronger and more wear-resistant than directly threading into plastic.

These inserts are engineered to grip firmly within the printed part, preventing rotation and pull-out. They are ideal for applications requiring repeated assembly and disassembly, making them perfect for enclosures, brackets, mechanical components, robotics projects, and functional 3D printed designs.

Compatible with most common 3D printing materials including PLA, PETG, ABS, ASA, and Nylon, these inserts are typically installed using a soldering iron or dedicated heat-set insert tool for a clean, permanent fit.
