Product Details

✓【Packaging】: Each set includes 40 high-quality brass threaded inserts, each measuring M4x8.1x6.3, accompanied by a soldering iron tip for easy installation.

✓【Premium Material】: Crafted from high-quality brass, these threaded inserts ensure durability and excellent performance, making them ideal for various 3D printing plastic materials.

✓【Easy to Use】: Pre-drill a pilot hole in the target plastic material. Using a soldering iron, heat up the insert until the surrounding plastic begins to soften. Align it with the pilot hole and firmly press it into the plastic material. Apply slight downward pressure to ensure proper embedding. Allow it to cool down and solidify within the plastic material.

✓【Versatile Application】 These threaded inserts are perfect for a wide range of applications, such as securing parts in 3D-printed prototypes, reinforcing plastic joints, or adding threaded inserts to plastic components.

✓【Reliable Fastening Solution】: By embedding these threaded inserts, you can achieve a strong and reliable connection, enhancing the structural integrity of your plastic products and ensuring they withstand stress and tension.
