Brass Heat Set Inserts for Plastic Materials

The 40/DM Brass Threaded Insert is designed to create strong, durable metal threads in plastic components. Manufactured from high-quality brass, these inserts are specifically engineered for use with thermoplastic materials and provide a reliable threaded fixing point for repeated assembly and disassembly.

Once installed, the insert allows two components to be securely joined using a standard male threaded screw or bolt. Unlike glued or press-fit alternatives, heat-set and ultrasonic installation methods create a secure mechanical bond within the plastic, delivering superior pull-out resistance and long-term performance.

Ideal for Thermoplastic and Injection Moulded Components

The 40/DM insert is designed for installation using thermal or ultrasonic insertion techniques. Simply pre-drill the plastic component to the correct hole size and install the insert using the appropriate method. As the plastic softens during installation, it flows around the insert, creating a strong mechanical bond without causing stress fractures or weakening the surrounding material.

This makes heat-set inserts an excellent solution for applications requiring durable, reusable threads in injection moulded plastics, engineered polymers, and 3D printed components.

Why Choose Brass Heat Set Inserts?

Brass heat set inserts provide a permanent, high-strength threaded fixing point in plastic materials. Installed using thermal or ultrasonic processes, they create a secure bond within the parent material, delivering significantly greater durability and pull-out resistance than glued or press-fit alternatives. They are ideal for applications requiring repeated assembly and disassembly without damaging the plastic component.
