Upgrade Your 3D Prints with Professional Heat Set Insert Tips
Get rock-solid, threaded connections in your 3D-printed plastic parts with this comprehensive Heat Set Insert Soldering Iron Tip Kit. Covering the most commonly used sizes — M2, M2.5, M3, M4, M5, and M6 — this 6-piece brass tip set pairs with your existing soldering iron to effortlessly embed threaded brass nuts directly into PLA, ABS, PETG, and other thermoplastics. Say goodbye to stripped screw holes and weak joints forever.
Made in Mainland China.
Why Use Heat Set Inserts?
Heat set (hot melt) brass inserts create far stronger, more durable threaded connections in plastic compared to self-tapping screws. By using heat to press the insert flush into your part, you get a metal-to-plastic bond that distributes load evenly and resists pull-out forces — ideal for enclosures, robotics, prototypes, and functional prints.

Frequently Asked Questions
Q: What soldering iron temperature should I use for heat set inserts in PLA?
A: For PLA, a soldering iron temperature between 180°C–220°C (356°F–428°F) is typically recommended. Start at a lower temperature and increase gradually to achieve a clean, flush insert without scorching the surrounding plastic material.
Q: Are these heat set insert tips compatible with all soldering iron brands?
A: These tips are designed to fit standard soldering iron handles that accept threaded or friction-fit tips. They are rated for 220V Europe/Korea standard irons. Please verify the thread and connector type of your soldering iron before purchasing to ensure compatibility.
Q: Can I use these tips with materials other than PLA in 3D printing?
A: Yes! These brass heat set insert tips work with a wide range of thermoplastics commonly used in 3D printing, including ABS, PETG, Nylon, TPU, and more. Simply adjust your soldering iron temperature to suit the specific melting characteristics of your filament material.
Q: What sizes of heat set inserts do these tips support?
A: This kit includes 6 tip heads to support the most common heat set insert sizes: M2, M2.5, M3, M4, M5, and M6. These cover the vast majority of standard metric threaded inserts used in 3D printing and DIY fabrication projects.
