M6 Brass Knurled Threaded Insert

This M6 Brass Knurled Threaded Insert is a heat-set fastener designed to add a strong, reusable metal thread to 3D printed and injection-molded plastic parts. Ideal for hobbyists, makers, and engineers working with PLA, PETG, ABS, and similar thermoplastics, this insert solves the common problem of stripped or worn-out threads when screws are driven directly into plastic. Installation is simple: using a soldering iron or heat-set tool, the insert is pressed into a pre-drilled or printed hole, melting the surrounding plastic so it flows around the knurled body and locks the insert permanently in place once cooled. The double-helical knurled exterior maximizes grip and pull-out resistance, while the brass construction offers excellent thermal conductivity for fast, clean installation along with long-term durability and corrosion resistance. This insert is well-suited for enclosures, brackets, robotics projects, RC builds, and any application requiring repeated assembly and disassembly without degrading the plastic threads. Its 8mm length and 8mm outer diameter provide a solid mounting depth for medium-duty applications, delivering a secure, professional-grade M6 thread that holds up reliably under repeated use.
