C3604 Brass Hot Melt Insert Knurled Nut for Plastic M3x10x4.5mm (5PCS/Bag)
The C3604 Brass Hot Melt Insert Knurled Nut is designed for creating durable M3 internal threads in plastic components. It is installed by heating the insert and pressing it into a properly sized hole in thermoplastic material. After cooling, the plastic securely grips the knurled outer surface, creating a strong and reliable threaded mounting point.
This insert is made from C3604 brass and features an M3 internal thread with a knurled external body for improved resistance against rotation and pull-out. With a 10mm length and 4.5mm outer diameter, it is suitable for 3D printed parts, plastic enclosures, electronic projects, robotics, and other applications requiring repeated assembly using M3 screws.
