Brass Heat Insert Nut Tips M2–M8 | 7-Pc 3D Printer Kit
Brass Heat Insert Nut Iron Tip Kit – M2 to M8 | 7-Piece Set
Upgrade your 3D printing and plastic fabrication projects with this professional-grade Brass Heat Insert Nut Iron Tip Kit from SEamopar. Designed to work seamlessly with standard 936 universal soldering irons, this 7-piece set lets you embed threaded brass nuts cleanly and precisely into plastic parts — no drilling press required. Whether you're finishing a 3D printed enclosure, prototyping a custom bracket, or assembling RC components, these tips deliver reliable, flush results every time.
What's in the Box: 1 box = 7 interchangeable iron tip indenters
Key Features
- Wide Size Compatibility: Supports M2 (shared with M2.5), M3, M4, M5, M6 (1/4"), and M8 hot-melt nuts and threaded inserts — one kit covers nearly every common size.
- 936 Soldering Iron Compatible: Fits all standard 936 universal soldering iron handles — simply swap out your existing tip and get to work.
- Female-Female Knurled Joint Design: Hand-twist knurled connectors let you swap threaded indenters quickly in the cooled state — no tools needed for changeover.
- Premium Brass Construction: CNC-machined brass delivers excellent heat conductivity, end-face contact that keeps nuts from skewing during insertion, and long-lasting durability.
- Precision Embedding Geometry: The tip head is engineered to seat slightly recessed after pressing, protecting surrounding plastic from surface damage while still seating the insert to the correct depth.
- Made in Mainland China

Frequently Asked Questions
Q: What soldering iron is compatible with this heat insert nut tip kit?
A: This kit is fully compatible with standard 936 universal soldering iron handles. Simply remove your existing soldering tip and replace it with one of the 7 included brass heat insert tips. No adapters are needed.
Q: Can I use these tips for sizes other than M3 and M4?
A: Yes! The kit covers M2 (also fits M2.5), M3, M4, M5, M6 (which also fits 1/4" imperial inserts), and M8, giving you full flexibility across the most common metric thread sizes used in 3D printing and plastic fabrication.
Q: How do I switch between tip sizes?
A: Allow the iron tip to cool completely, then hand-twist the knurled joint to unscrew the current indenter head and thread on your desired size. No tools are required — the knurled grip makes swapping fast and easy.
Q: Will these tips damage the plastic parts during insertion?
A: The tips are precision-engineered with a recessed-embed geometry that seats the nut at the correct depth while minimizing contact with surrounding plastic surfaces, helping to keep your printed parts looking clean and professional.
