Key locked inserts, also called key-locking threaded inserts, are fasteners used to create robust threaded connections in materials like metal, plastic, or composite. They feature a threaded metal body with external splines or keys for enhanced resistance to rotation and pull-out forces. Installation involves inserting them into a pre-drilled hole and using a special tool to lock them securely into place. These inserts are prized for their high torque and pull-out resistance, making them ideal for applications in aerospace, automotive, electronics, and machinery manufacturing.
