Anchor nuts are self-locking fasteners equipped with an integrated plate that can be riveted to a surface, enabling bolts to be installed from one side. This design makes them especially useful in confined or hard-to-reach areas. The built-in locking mechanism ensures secure fastening, while the plated base provides added stability during installation. They allow quick and efficient assembly in aerospace, automotive, and sheet metal applications, and their reusable threaded design helps minimize wear while maintaining long-term reliability.
