Quickly and easily repair stripped or damaged threads, or create stronger original threads in die castings or plastics with our Helical Screw Thread Inserts. Coil tension securely holds the insert in place without undue tension on the surrounding material. The inserts are vibration and impact resistant. Made from corrosion resistant stainless steel, they offer a wide temperature tolerance.
Helical Inserts are often known by the brand names Helicoil or Recoil Screw Thread Inserts. Our Precision Thread Helical Inserts are interchangeable with other brands of inserts and tooling. If you are currently using Helicoil, Recoil, or Mil Spec part numbers for your inserts, please see our Cross Reference Numbers below for an easy and accurate transition to our Precision Thread Helical Inserts from Chrislynn.

Threads on the exhaust of my raptor go-kart engine were stripped out. This kit helped me to bring the threads back to better then new. Instead of aluminum they are now stainless steel. This kit worked perfect !
