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.
