Helical Inserts

Helical inserts, also known as screw thread inserts or Heli-Coils, are innovative threaded devices designed to reinforce and repair damaged or worn threads in metal components. Typically made of stainless steel or other durable materials, these inserts feature a helical coil shape with an external thread that matches the parent material and an internal thread to accommodate screws or bolts. Helical inserts effectively distribute loads, enhance thread strength, and prevent loosening caused by vibration or stress. Widely used in aerospace, automotive, and manufacturing industries, these inserts provide a cost-effective solution for thread repair, improving the overall durability and longevity of threaded connections.
