The Thread Repair Insert is used to repair or reinforce damaged internal threads in assemblies. It is installed into a pre-tapped hole, where it forms a new internal thread that matches the original fastener size and pitch. During installation, the insert expands slightly and locks into place, creating a firm and stable threaded surface for bolts or screws. The insert maintains consistent thread engagement, allowing fasteners to be tightened securely and removed repeatedly without causing further damage to the base material.Attributes:• Prevents cross-threading by maintaining defined thread geometry.• Maintains consistent thread pitch for proper fastener fit.• Maintains proper thread engagement for consistent tightening performance.Applications: The Thread Repair Insert is used in threaded holes where internal threads are damaged or worn, such as in cylinder heads and other mechanical housings. It is installed into the existing hole to restore the thread so that fasteners can be securely fitted and function properly.
