Thread-forming screws according DIN 7500 can be driven into malleable materials without the need for tapping the mating thread.
Whether a certain type of thread-forming screw is suitable for a given malleable material (steel, aluminium or non-ferrous metal) should be tested and evaluated through application testing.
Bossard engineers carry out application testing to assess thread froming screws, sizes M2.5 to M8, for your specific applications.
Findings and recommendations are finally documented in a test report.
