Upgrade your 3D printed projects with heat-set threaded inserts designed for secure, reusable fastening in thermoplastic parts. These knurled nuts are installed by heat embedding or manual insertion, helping create strong threaded mounting points for assemblies, panels, and printed accessories.
Available in several metric sizes and pack options, they are a practical choice for makers, repair work, custom fabrication, and 3D printer projects such as Voron 2.4 builds. The external knurling helps the insert grip the surrounding printed material while the internal thread accepts matching metric screws.
Use the selected insert size with a compatible metric screw. For heat installation, carefully embed the nut into the printed part using suitable controlled heat equipment. Manual insertion is also possible where the design and fit allow it.
