Brass Heat Set Threaded Inserts for Plastic Components

The 40/TH Brass Heat Set Insert is designed to provide a strong, durable threaded fixing solution in plastic components. Manufactured from high-quality brass, these inserts create reliable, reusable metric threads that allow plastic parts to be securely assembled using standard male threaded bolts.

Designed for installation using thermic (heat) or ultrasonic insertion methods, these threaded inserts become securely embedded within the plastic material, creating a permanent fixing point with exceptional pull-out resistance. Unlike gluing or press-fitting methods, heat set inserts minimise stress fractures and material weakness, resulting in a stronger and more reliable assembly.

Ideal for Plastic Components and Repeated Assembly Applications

40/TH brass inserts are ideal for use in thermoplastics where a durable metal thread is required. Once installed, they provide a robust threaded connection capable of withstanding repeated assembly and disassembly without damaging the parent material.
