About this item
- 【Complete 350-Piece Kit】Includes 6 soldering iron tips (M2, M3, M4, M5, M6, M8), two connecting rods for thermal tips, 1 soldering iron, and 350 threaded inserts made of brass. Comes with tweezers for easy handling of small parts like M2. The extensive range of Brass Metric Knurled Nuts is great for 3D printing accessories.
- 【Stable and Durable Threaded Inserts】The nut inserts kits are made of high-quality brass, ensuring optimal corrosion resistance and excellent thermal conductivity. Each threaded insert is easy to use and offers a long service life. Specially designed for thermoplastics, these inserts securely fix into materials such as PLA, PETG, ABS, PPS, and PP. Once the plastic cools and hardens around the brass sleeve, the insert remains firmly in place.
- 【Upgraded Soldering Iron Version】: This heat insert assortment set features an improved soldering iron handle. The new model, specially designed for 3D printer accessories, includes a power indicator light and an on/off control button. It heats up faster, with enhanced thermal accuracy and optimized temperature regulation during prolonged use. Specifications: 60W power, adjustable temperature range from 200 to 500°C.
- 【Practical Design for Thermal Tip Replacement】The connecting rod allows easy switching between thermal tips of different sizes without having to remove the entire soldering iron sleeve. Simply unscrew the old tip and replace it with a new one. Compared to other kits, the inclusion of an additional connecting rod makes changing Threaded Inserts of various dimensions even more convenient.
- 【Threaded Insert】A hot connector for Threaded Inserts, which can be inserted into the soldering iron head through rapid heating, melting the plastic and embedding the nut firmly into the plastic, creating a new screwable thread. The connecting bar allows easy switching from one soldering iron head to another without having to remove the entire soldering iron housing.

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.
