Threaded Inserts

Threaded inserts are fasteners that provide secure and reusable threaded holes for screws and bolts when the base material is not strong enough to ensure long-lasting durability. They are commonly used in softer materials such as soft metals, alloys, plastics, composites, and woods where native threads can break or deform when mated screws and bolts are over-tightened.

Threaded inserts are typically made from brass, stainless steel and aluminum. Materials are chosen by corrosion resistance, heat resistance, vibration resistance, thermal expansion compatibility, and other factors, depending on their compatibility with the base material.

Heat Set Inserts vs. Ultrasonic Inserts: Optimizing Fastener Selection for Injection Molded Plastic Assemblies

Threaded Inserts Set in Plastic

Fastener selection plays a vital role in determining long-term part integrity, assembly repeatability, and structural performance. Among the most widely used fastening methods for thermoplastics are heat set inserts and ultrasonic inserts. Both methods deliver durable, threaded metal connections, but they differ in how they interact with molded materials and
