- 【High-Quality Brass Construction for Durability】Ensure long-lasting thread strength in your plastic projects. These threaded inserts are precision-machined from solid brass, offering excellent corrosion resistance and the ability to withstand temperatures up to 300°C during the heat-set installation process, making them far superior to plastic threads for repeated assembly and disassembly.
- 【Spiral Knurl Design for Maximum Anti-Rotation Grip】Prevent inserts from spinning or pulling out under stress. The exterior of these threaded inserts features a sharp, opposing spiral knurl pattern. When heat-set into the plastic, these knurls bite deep into the material, creating an incredibly strong mechanical lock that resists rotational forces and ensures your screws stay securely fastened.
- 【Simple Heat-Set Installation with a Soldering Iron】Embed strong threads in seconds with common tools. Installation is straightforward: heat the brass insert with a soldering iron tip to around 250-300°C, then gently press it into a pre-drilled or printed hole in your ABS, PLA, PETG, or Nylon part. The plastic melts around the knurls, forming a permanent bond as it cools.
- 【Multiple Size Options for Every Project】Choose the perfect fit for your build. Available in M2x4x3.5 (100pcs), M3x5x5 (100pcs), M3x4x5 (100pcs), and M4x6x6 (100pcs) individual packs. Need variety? Grab the complete M2-M6 assorted kit with 400 pieces total – perfect for keeping your workshop stocked for any project that comes your way.
- 【Ideal for Reinforcing 3D Printed & Plastic Components】The professional solution for weak plastic threads. These metric threaded inserts are specifically designed to solve the problem of stripped threads in thermoplastic materials. They are perfect for Voron and other 3D printer frames, CNC-machined parts, model making, prototyping, and any application where you need a reliable, metal-threaded connection in plastic.
