From the shop's description

C3604 Brass Hot Melt Insert Knurled Nut for Plastic M3x6x4.2mm (5PCS/Bag) The C3604 Brass Hot Melt Insert Knurled Nut is designed to add a durable internal M3 thread to plastic components. Its knurled outer surface provides strong mechanical engagement with the surrounding plastic after the insert is installed by heat, making it suitable for creating secure threaded mounting points in 3D-printed and molded plastic parts. Made from C3604 brass, this insert offers good machinability, corrosion resistance, and reliable thread durability for repeated assembly and disassembly. The compact 6 mm length and 4.2 mm outer diameter make it suitable for applications where a relatively small threaded insert is required without adding excessive material to the plastic component. Features: Designed for heat insertion into plastic components. Knurled exterior provides strong grip inside plastic. Creates a reusable threaded mounting point. Suitable for repeated screw installation and removal. Compact design for space-constrained assemblies. Suitable for 3D-printed and molded plastic parts.
