heli coil , Iran
A Helicoil is a metallic threaded insert for repairing and reinforcing damaged internal threads. It is made from Austenitic stainless steel wire such as AISI 302/304 or Inconel X-750 alloy with a square or diamond cross-section. The wire diameter typically ranges from 0.6 to 2 mm, graded according to ISO 9001:2015. Helicoils are available in metric M2 to M48 and unified UNC/UNF thread sizes. The ultimate tensile strength of standard steel inserts is at least 1400 MPa. Installation requires creating a starter thread using a special drill and tap steyer. After installation, the inserts back-out torque is up to 40% higher than the original threads. This feature secures the connection against vibration-induced loosening.
The Helicoil structure is a spring-like coil with a 90-degree wind angle and a short lead-in tang. Surface coatings like silver or PTFE are sometimes used to reduce friction and improve electrical properties. According to aerospace standards like NASM 33575 or MS 21209, it must withstand temperature cycles from -55°C to +260°C. Quality control tests include torsional tension, sealing tests, and salt spray corrosion resistance checks. Its primary applications are in aircraft engines, braking systems, and aluminum cylinder blocks. The inserts are permanently locked into the base material using special tools e.g., Inserter and Tang Break Off. Their service life typically exceeds 5000 screw fastening cycles.You can order and buy heli coil from Iran by contacting us through whatsaap and email.

Industrial Applications of Helicoil
Helicoil is used as a thread repair and internal reinforcement insert in various industries. In the automotive and aerospace industries, it is critical for restoring worn threads in engine blocks, cylinders, and body components. The heavy machinery industry uses it to repair and enhance the strength of bolt threads in components under stress and vibration. In the marine and chemical industries, it is employed to protect threads from corrosion in connections such as flanges, valves, and pumps. Medical and dental equipment utilize Helicoil to create precise and corrosion-resistant threads in surgical instruments and implants. It is also widely used in tool and industrial mold repair to prevent damage to the original component. The materials used are often stainless steel, bronze, or Inconel, chosen according to the working environment.
