Thread-locking inserts are specialized mechanical fasteners that provide thread locking capability while retaining the ability to be reused. These inserts have a threaded stud which is designed to work with either internal or external threads and feature an elastic flexible core, made from carbon steel, which expands when tightened to create a permanent thread. They are ideal for use in applications where the replacement of lost or damaged screws is required without having to replace the entire component. Thread-locking inserts reduce assembly time and offer superior performance in securing fasteners compared to traditional lock nuts, making them perfect for use in industrial applications.
