Helical Wire Thread Inserts

Stripped threads in expensive aluminum or cast iron components no longer mean the part is scrapped. Our Helical Wire Thread Inserts are precision-formed coils of diamond-shaped stainless steel wire that create a brand-new, high-strength internal thread. By installing these into an oversized hole, you actually create a thread that is stronger and more wear-resistant than the original material. We have spent two decades in Shanghai perfecting the elasticity and hardness of these inserts.

The durability of our Helical Wire Thread Inserts is unmatched. Made from SUS304 with a hardness of HRC 43-50, these inserts protect the base material from galling and thread fatigue. In soft alloys, they can increase thread load-bearing capacity by up to 100%. Our Helical Wire Thread Inserts are compatible with all major thread repair systems and operate reliably from -60°C to +300°C. Whether you are reinforcing a new design or performing a critical repair, our inserts provide the ultimate threaded interface.
