Helicoil® Thread Inserts provide a permanent, high‑strength internal thread solution for materials such as aluminium, magnesium, cast iron and plastics. Manufactured from precision‑formed stainless steel wire, Helicoil inserts create wear‑resistant threads that exceed the strength of the original tapped hole. They are ideal for load‑bearing, high‑cycle and service‑critical applications, offering improved resistance to stripping, vibration and fatigue. Widely used in automotive, aerospace, general engineering and industrial maintenance environments.
