M3 M4 Stainless steel wire thread insert SUS304 SUS316 A2-70 A4 for Automotive Mechanical
A wire thread insert (also known as a helical thread insert or coil insert) is a mechanical component used to repair or reinforce damaged or worn threaded holes. Made from high-strength stainless steel wire with a coiled design, it restores or strengthens original threads for secure fastening of bolts and screws.
- Thread Repair: Recreates original threads in stripped or damaged holes
- Thread Strengthening: Provides additional support in softer materials like aluminum
- Damage Prevention: Distributes loads evenly to prevent stripping
- Corrosion Resistance: Stainless steel construction for harsh environments
