C3604 Brass Hot Melt Insert Knurled Nut for Plastic M3x12x5mm (5PCS/Bag)
The C3604 Brass Hot Melt Insert Knurled Nut is designed to provide a durable M3 internal thread in plastic components. It is installed by heating the insert and pressing it into a properly sized hole in thermoplastic material. Once the plastic cools, it securely grips the knurled outer surface, creating a reliable threaded mounting point.
Made from C3604 brass, this insert features an M3 internal thread, a 12mm length, and a 5mm outer diameter. The knurled body helps improve resistance against rotation and pull-out, making it suitable for applications that require repeated assembly and disassembly with M3 screws, including 3D printed parts, plastic enclosures, robotics, and electronic projects.
