What Are Threaded Inserts?
Thread inserts are fastening components used to reinforce or repair threaded connections, especially in soft materials such as plastic, aluminum, or magnesium. They are installed into a base material to provide strong, wear-resistant threads. Thread inserts can be embedded during the molding process or installed afterward using methods such as heat staking, ultrasonic insertion, or self-tapping.
Main Functions of Thread Inserts:
Enhancing Thread Strength: Create strong internal threads in soft materials, preventing stripping or thread failure.
Repairing Damaged Threads: Restore worn or stripped threads, extending the lifespan of the component.
Improving Wear Resistance and Reusability: Ideal for applications that require frequent assembly and disassembly.
Distributing Load: Help distribute stress in high-load applications, reducing the risk of material cracking or deformation.
Common Types:
Wire Thread Inserts: Such as Heli-Coil types, made from high-strength wire coiled into a helical shape.
Solid Thread Inserts: Machined from solid metal, often used in metal substrates.
Self-Tapping Inserts: Can cut their own threads during installation without the need for pre-tapped holes.
Heat-Set Inserts: Installed into thermoplastics by heating, commonly used in plastic components.
