HELI-COIL® works hard for you
Get stronger, more robust connections and repairs
Deliver strength, precision and performance
For your aerospace, military, automotive and other critical applications, enhance every connection with the added strength of Heli-Coil threaded inserts. A straightforward choice for repair of stripped threads, threaded inserts are also increasingly specified for tapped holes in original manufacturing.
Unlike standard tapped holes—which tend to rely on just the first 2-3 threads—Heli-Coil inserts distribute the load across every thread for a stronger, more durable assembly. With Heli-Coil you'll create a better product, enjoy a lower rate of returns and increase customer satisfaction.
Choose "The Original" for superior performance
Heli-Coil inserts—the Original wire thread inserts—are the engineer's choice for reliable tapped holes. These high-quality products offer serious benefits for superior performance.
