## Features

- Suitable for 3D printing: Brass threaded inserts, which can be embedded into plastic materials using the heat from a soldering iron or ultrasound, are the optimal solution for adding threads in 3D printing.
- Common specifications: We have created this set of inserts using M2 M3 M4 M5 sizes based on the most commonly used specifications by 3D printing enthusiasts. The heights range from 3mm to 12mm. We hope you will like it.
- Secure fixation: Our brass threaded inserts are made of high-quality brass and undergo precision processing, ensuring excellent heat conduction and corrosion resistance. Through testing, we have found that compared to straight-threaded inserts, the knurled threaded inserts provide stronger gripping strength and can withstand high levels of tensile force.
- Clear labeling: Each specification has its own independent compartment in the plastic box, and we have attached labels with detailed annotations for key data, making it convenient to use.
- Brand guarantee: Kadrick specializes in the production and development of fasteners. Our products have undergone rigorous testing, so you can use them with confidence. Additionally, we provide a 24-month after-sales warranty service. If you have any questions, please feel free to contact us.
