Brass Heat Set Inserts for Plastic Materials

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

Featuring a double stripe body with collar, these inserts offer excellent retention within the parent material while creating a secure and reusable metric thread. Once installed, the insert allows two components to be fastened together using a standard male threaded screw or bolt, providing a professional and long-lasting fastening solution.

Unlike glued or press-fit alternatives, heat-set and ultrasonic installation methods create a strong mechanical bond within the plastic, delivering superior pull-out resistance and long-term durability.

Ideal for Thermoplastic and Injection Moulded Components

The 40/DCC insert is designed for installation using thermal or ultrasonic insertion processes. Simply pre-drill the plastic component to the correct hole size and install the insert using the appropriate equipment. As the plastic softens during installation, it flows around the insert's external features, creating a secure fixing without causing stress fractures or weakening the surrounding material.

This results in a stronger and more reliable fastening solution compared to traditional press-fit or adhesive-based methods.
