M3 Brass Insert Nut (100 Nos) 3mmX5mm

The M3 Brass Insert Nut is a high-quality threaded insert designed to create strong, durable, and wear-resistant threads in plastic components. Manufactured from premium brass with a precision knurled exterior, it provides excellent grip and prevents rotation or pull-out after installation. It is widely used in 3D printed parts, injection-molded components, electronic enclosures, robotics, drones, automotive assemblies, and industrial products.

Designed for heat-set or press-fit installation (depending on the model), the M3 insert nut offers reliable fastening for repeated assembly and disassembly without damaging the surrounding material.
