Brass Heat Set Inserts for Plastic Materials
The 40/TR 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 thermoplastics, providing a reliable and reusable threaded fixing point for repeated assembly and disassembly.
Once installed, the insert allows two products to be securely fastened together using a standard male threaded screw or bolt. Unlike glued or press-fit alternatives, heat-set and ultrasonic installation methods create a permanent mechanical bond within the plastic, delivering superior pull-out resistance, torque performance, and long-term reliability.
Ideal for Thermoplastic and Injection Moulded Components
The 40/TR insert is designed for installation using thermal (heat-set) or ultrasonic insertion processes. Simply pre-drill the plastic component to the recommended hole size and install the insert using the appropriate equipment. During installation, the plastic softens and flows around the insert body, creating a secure fixing without causing stress fractures or weakening the surrounding material.
The insert geometry is specifically designed to create an expansion and self-breaking effect within the plastic material. This increases pull-out resistance and torque performance by creating a stronger mechanical engagement between the insert and the parent material. The result is a durable threaded fixing that offers significantly greater strength and reliability than conventional glued or press-fit alternatives.

Why Choose 40/TR Brass Heat Set Inserts?
40/TR Brass Heat Set Inserts provide a permanent, high-strength threaded fixing point in plastic materials. Installed using thermal or ultrasonic methods, they create a secure bond within the parent material while the insert profile generates an expansion and self-breaking effect, improving resistance to pull-out and rotation. This delivers significantly greater durability and fastening strength than glued or press-fit alternatives, making them ideal for applications requiring repeated assembly without compromising the integrity of the plastic component.
Product Summary
The 40/TR Brass Heat Set Insert provides strong, reusable metric threads in plastic materials. Designed for thermal and ultrasonic installation, these brass inserts utilise an expansion and self-breaking retention effect to maximise pull-out resistance and long-term durability. Ideal for injection moulded, engineered plastic, and 3D printed components, they are available in M2 to M10 sizes.
