AU$25.87
The Plexa Brass Heat-Set Insert Kit is a complete threaded insert solution for 3D-printed parts that require strong, repeatable fastening.
These knurled brass inserts are designed to be heat-installed into thermoplastics, allowing them to melt cleanly into printed parts and form durable metal threads. This provides significantly better strength and wear resistance compared to self-tapping screws.

We try our very best to be competitive in pricing but we also need to pay wages, rent, taxes and pay for the bad stuff, like dead stock, shrinkages, fraud and importing challenges. However, we forget all this when we are able to help cure treat your FPV addiction 🙂
