Working Mechanism

  • E-Z Lok thread repair kits use the thread locking process that involves installing a threaded insert into the stripped / damaged thread.
  • The insert, made of harder and more durable material, is designed to fit tightly into the damaged thread.
  • Once the insert is in place, it creates a new, stronger thread that can secure bolts and other fasteners.
  • The kit includes an installation tool to install the insert into the damaged thread. This tool compresses the insert as it is being inserted causing it to expand and lock into place.

Frequently Asked Questions

How many times can I use this thread repair kit?

E-Z LOK thread repair kits provide a permanent bond, so they only need to be used once. However, in some cases, the repair may need to be redone if the thread insert becomes loose over time due to external factors.

What are self-locking inserts?

Self-locking inserts allow permanent repair without the need for external locking devices. They have a barbed or knurled surface on the outer diameter that creates a mechanical interlock between the insert and the surrounding material during installation. The interlock creates a secure connection that can withstand high loads and vibrations.

What is a tang break-off tool?

A tang tool is needed to remove the driving tangs of inserts to avoid their interference with the end of the assembled bolt. It is automatically operated using a spring-loaded, easily triggered punch that strikes a sharp, uniform blow against the tang of the installed insert.
