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.
