How the heat-shrink nut heating kit works

When using this product, please ensure it is held vertically against the plastic surface to minimise the risk of it tilting.

【Threaded Inserts】A heat-set connection tool kit for threaded inserts. Equipped with a heating soldering iron and a full set of M2-M8 nuts, it can be rapidly heated and embedded into the plastic, melting the material and securely embedding the nuts to create new, screwable metal threaded holes.
【Flexible Design】The connecting rod allows easy switching between different soldering tips without disassembling the entire soldering gun housing.

【Stable and Durable】The threaded inserts are made of the highest quality brass, ensuring excellent corrosion resistance and good thermal conductivity.
【Wide Application】Threaded inserts are suitable for all thermoplastic materials. For example, knurled nuts can be applied to materials such as PLA, PETG, ABS, PPS, PP, etc.
