TIME-SERT vs Helicoil – Which Is Better?

When comparing TIME-SERT® and Helicoil® thread-repair systems, the distinction lies in design and longevity. TIME-SERT® uses a solid bushing insert with a flanged collar for full thread engagement and vibration resistance. By contrast, Helicoil® employs a wire-coil insert that can unwind or loosen under torque. Therefore, TIME-SERT® delivers a stronger, more permanent repair that withstands high stress and thermal expansion—making it ideal for oil-drain plugs, sump repairs, and critical engine components.

Application and Instructions

Begin by drilling out the damaged thread using the included drill bit. Next, counterbore the hole to form a seat for the insert flange. Then, tap new threads with the supplied tap tool. Apply driver oil, insert the flanged bushing, and drive it into position with the insertion tool until it locks firmly in place. As a result, you achieve a flush, permanent, and pressure-tight repair. For more thread-repair solutions, visit our TIME-SERT Inserts collection.
