M8 M10 Stainless steel wire thread insert SS304 SS316 A2 A4-80 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 reduce stripping
- Corrosion Resistance: Stainless steel construction withstands harsh environments

304 and 316 are austenitic stainless steels with excellent corrosion resistance. The "L" variants (304L, 316L) have lower carbon content to reduce intergranular corrosion susceptibility, particularly important in high-chloride environments.
Available in small packing, carton packing, or pallet options. Standard package contains 100 pieces. Shipped from Shenzhen port after quality inspection.
Manufactured by JIA SHAN Hardware Company, a specialist in high-quality stainless steel fastening solutions.
