Brass Heat Set Inserts for Plastic Materials
The 40/TS Symmetrical SERPLAST Brass 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.
Designed for installation using thermic (heat-set) or ultrasonic processes, the symmetrical SERPLAST design allows the insert to become securely anchored within the parent material. Once installed, the insert provides a strong and reusable metric thread, allowing components to be repeatedly assembled using standard male threaded fasteners.
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/TS insert is designed for installation using thermal (heat-set) or ultrasonic insertion techniques. Simply pre-drill the hole to the recommended size and install the insert using the appropriate equipment. During installation, the plastic softens and flows around the insert geometry, creating a secure fixing without introducing stress fractures or weakening the surrounding material.
The symmetrical SERPLAST profile creates an expansion and self-breaking effect within the plastic material, improving retention and increasing resistance to pull-out and rotational forces. This mechanical engagement provides a stronger and more durable fixing compared with traditional glued, adhesive-based, or press-fit fastening methods.

Why Choose TS Symmetrical SERPLAST Brass Inserts?
TS Symmetrical SERPLAST Brass Inserts provide a permanent, high-strength threaded fixing point in plastic materials. Installed using thermic or ultrasonic processes, they create a secure bond within the parent material while the insert profile generates an expansion and self-breaking effect that improves pull-out resistance and torque performance. This results in a fastening solution that delivers significantly greater durability and reliability than glued or press-fit alternatives.
Product Summary
The 40/TS Symmetrical SERPLAST Brass Insert provides strong, reusable metric threads in plastic materials. Designed for thermic 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.
