TIME-SERT vs Helicoil – Which Is Better?

When comparing time-sert metric inserts and Helicoil® systems, the difference lies in both strength and precision. TIME-SERT® uses a solid flanged bushing that locks permanently into place, delivering superior vibration resistance and load capacity. In contrast, Helicoil® relies on a wire-coil design that can unwind or loosen under torque and heat. Therefore, TIME-SERT® ensures a more reliable, professional-grade repair—ideal for critical applications requiring precision, durability, and long-term stability.
