About this item
- [COMPLETE 206PCS KIT — EVERYTHING YOU NEED] Stop searching for separate tools. This comprehensive assortment kit provides 206pcs of heat set inserts in M2, M3, M4, M5, and M6 sizes, plus a dedicated soldering tip and adapter. Whether you're working custom DIY robotics, this all-in-one solution ensures you have the right hardware for any plastic embedding project.
- [PRECISION DOUBLE TWILL — INDUSTRIAL-GRADE GRIP] Engineered for high-torque applications, our M3 to M6 nuts feature a 45-degree double diagonal knurling design. This advanced structure creates a deep mechanical interlock within 3D printed components, delivering superior pull-out resistance. Experience a professional, long-lasting hold that effectively withstands heavy vibration and dynamic loads.
- [ELECTROPLATED BRASS — EFFICIENT HEAT TRANSFER] Optimized for rapid installation, these threaded inserts are made of premium electroplated brass for superior thermal conductivity. The smooth finish allows the hardware to be embedded cleanly into PLA, ABS, or PETG at high temperatures. The electroplating also provides enhanced corrosion resistance for automotive or outdoor engineering use.
- [BURR-FREE THREADS — SEAMLESS COMPATIBILITY] Eliminate the frustration of stripped or misaligned threads. Each knurled nut is precision-machined with deep, clean metric female threads for smooth screw insertion. Perfectly compatible with standard 3D printer hardware, these fasteners solve the alignment issues common in crude alternatives, ensuring your assemblies stay reliable.
- [ORGANIZED STORAGE — EASY SIZE IDENTIFICATION] Stay organized and efficient in your workshop. All 206 pieces are securely housed in a sturdy, transparent case with clear M2-M6 labels for quick identification. Compact and portable, this 3D printing tool kit is a must-have for engineers, hobbyists, and makers who demand precision and order in their hardware collection.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
