How Time-Sert Works
Understanding the Time-Sert installation process and unique locking mechanism.
The Time-Sert System
Time-Sert is a thin-walled solid steel insert that creates a permanent thread repair stronger than the original thread. Unlike helical wire inserts, Time-Sert becomes an integral part of the parent material through a unique roll-forming locking mechanism.
The insert features extra material in the bottom internal threads. During installation, this material is roll-formed outward to lock the insert permanently in place. This creates a mechanical bond that prevents the insert from loosening under vibration or thermal cycling.

Installation Process
Step 1: Drill Out Damaged Thread
Use the specified drill size to remove the damaged thread. The drill size is precisely calculated to provide the correct hole diameter for the insert's outer thread. Clean the hole thoroughly to remove all debris.
Step 2: Counterbore the Top
The Time-Sert counterbore tool creates a recessed lip at the top of the hole. This lip accommodates the insert's top flange and ensures the insert sits flush with or slightly below the surface. The counterbore depth is critical for proper installation.
Step 3: Tap New Threads
Use the Time-Sert tap to create new threads in the prepared hole. The tap is designed specifically for the insert's outer thread form. Tap to the full depth and back out carefully to ensure clean, complete threads.
Step 4: Install the Insert
Thread the insert onto the installation tool and drive it into the prepared hole. The driver tool controls the depth and ensures the insert seats properly in the recess produced by the counterbore. As the insert reaches the bottom of the hole, the installation tool applies controlled force to roll-form the final threads and lock the Time-Sert in place.
Step 5: Complete the Installation
The installation is complete when the insert's top flange is seated in the counterbored recess and the roll-formed bottom threads have been mechanically locked into the parent material. The insert is ready to accept a bolt immediately with no curing time required.
The Locking Mechanism
Time-Sert's unique locking mechanism differentiates it from other thread repair solutions. The bottom internal threads of the insert have extra material that extends into the parent material's threads during installation.
When the installation tool drives the insert home, it applies controlled axial force that roll-forms this extra material outward. This creates a mechanical interlock between the insert and parent material that cannot work loose.
The thin-wall design maximizes thread engagement while the solid construction prevents the insert from collapsing or deforming under load. This combination creates a repair that is stronger than the original thread.
Why Time-Sert is Permanent
Mechanical Lock: The roll-formed bottom threads create a permanent mechanical bond that cannot be reversed without removing material.
Solid Construction: Time-Sert prevent gas or fluid leakage in critical applications like sparkplugs and sump plugs.
Vibration Resistance: The mechanical lock prevents loosening under vibration or thermal cycling.
Load Distribution: The thin-wall design distributes loads evenly across all engaged threads.
