Heli-Coil inserts create stronger-than-original threads and distribute stress more evenly across the fastener. Once installed, the insert provides a permanent wear-resistant thread that accepts standard M5 x 0.8 bolts. The stainless steel construction resists corrosion and withstands high temperatures, making this kit ideal for exhaust system repairs and other demanding applications.
