            Introduction to the GB\/T 3098.14-2000 Standard GB\/T 3098.14-2000 specifies the mechanical properties of fasteners, focusing on the nut expansion test. This standard is essential for ensuring the ductility and integrity of nuts under mechanical stress, particularly in industries such as automotive, aerospace, and construction. The test evaluates the nut’s ability to withstand hole expansion without premature failure, providing critical data for material selection and quality control. As a mechanical materials expert, this procedure helps verify compliance with performance grades, preventing failures in high-load applications. The expansion test measures the percentage of hole diameter increase after removing internal threads and forcing a tapered mandrel through the nut.
