Brass Threaded Heat Insert Nut Kit for 3D Printers

Upgrade your 3D-printed parts with rock-solid, reusable threaded connections. This precision brass heat insert nut kit is designed for use with a standard soldering iron, allowing you to embed durable brass threads directly into plastic parts — giving you metal-strength fastening without cracking or stripping. Available in sets of 7, 9, or 10 pieces, covering the most common metric sizes: M2, M3, M4, M5, M6, and M8.

Why Choose Brass Heat Inserts?

  • Superior Holding Strength: Brass threads outlast plastic threads many times over, providing secure, long-lasting fastening in PLA, ABS, PETG, and other thermoplastics.
  • Easy Installation: Simply press the insert against your pre-drilled hole with a heated soldering iron tip — the brass melts in cleanly and locks in place as it cools.
  • Versatile Sizing: Includes M2, M3, M4, M5, M6, and M8 inserts to cover a wide range of 3D printing project needs.
  • Premium Brass Construction: Made from high-quality brass for excellent corrosion resistance and a clean gold finish.
  • Reusable & Reliable: Once set, these inserts allow bolts and screws to be removed and re-fastened repeatedly without wear.

Frequently Asked Questions

Q: What soldering iron temperature should I use to install these brass heat insert nuts?

A: Most brass threaded heat inserts work best between 180°C and 260°C (356°F–500°F), depending on the thermoplastic you're working with. For PLA, a lower temperature around 200°C is recommended; for ABS or PETG, slightly higher settings may be used. Always test on a spare piece first for best results.

Q: What plastic types are these heat inserts compatible with?

A: These brass heat insert nuts are compatible with most common 3D printing thermoplastics, including PLA, ABS, PETG, TPU, and Nylon. They are not suitable for thermoset resins or SLA/resin prints that do not soften with heat.

Q: How do I choose the right insert size for my project?

A: Match the insert size (M2, M3, M4, M5, M6, or M8) to the bolt or screw size you plan to use. Your 3D model's hole diameter should be sized slightly smaller than the outer diameter of the insert — the heat causes it to expand and grip snugly as it cools in place.
