      About Helical Inserts

      Helical Inserts are used to repair threads that have been worn or damaged. They are installed into a tapped hole and create an internal thread in the substrate, providing a strong and permanent thread repair.

      Types of Helical Inserts

      Helical Inserts come in many types, from free-running inserts to self-tapping inserts. The type of insert chosen depends on the application and the degree of wear or damage to the existing threads. Thread Repair Inserts can also be customized for specific needs.

      How Helical Inserts are Made

      Helical Inserts are typically made from high-strength steel wire that has been cold formed into a helix shape. This helix is then wound around a mandrel and heat treated for strength before being cut into individual inserts.

      Industries that use Helical Inserts

      Thread Repair Inserts are widely used across many industries, including automotive, aerospace, industrial manufacturing, oil & gas, and marine. Professionals rely on them as they provide an effective solution for repairing threads quickly and easily.
