The embedded nuts feature guiding elements, eliminating the need for countersinking or recessing, making your work more convenient and efficient.
- 【Easy to Use】- Brass threaded inserts can be installed into components of a 3D printer through heating or ultrasonic methods, or molded during the injection process. They are also suitable for circuit board assembly and the electronics field. With a common soldering iron, you can easily place them into the holes of 3D prints.
- 【Wide Application】 - These inserts are designed for use with all thermoplastics, including materials like PLA, PETG, ABS, PPS, PP, and others. Whether installing them in 3D printed objects, injection-molded plastic parts, automotive plastic casings, or laptop shells, these inserts offer reliable and durable solutions.
- 【Convenient Use and Storage】- Stored in reinforced compartmentalized boxes, all components are segregated to prevent mixing during transportation. Corresponding labels and compartments for the threaded inserts help you quickly find the desired type, significantly boosting your work efficiency.
