Thread repair inserts are also commonly known as threaded inserts or helicoil inserts. They are cylindrical metal components used to repair or reinforce damaged threads in a variety of materials, such as metal, plastic, or wood.
The thread repair insert consists of a helical coil that is threaded internally and externally. It is typically made of stainless steel, brass, or other durable materials. The external threads of the insert match the size and pitch of the damaged or stripped threads in the parent material. The internal threads of the insert are designed to accept the fastener that will be used in the repaired hole.
Thread repair inserts are used when the original threads have been stripped, worn out, or otherwise damaged, making it impossible to thread a bolt or screw into the material. Installing a thread repair insert is an effective solution to restore the strength and integrity of the threaded hole. The insert provides a new, durable, and reliable threaded surface for the fastener to grip, ensuring a secure and long-lasting connection.
