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 forming screws, sizes M2.5 to M8, for specifi c customer applications. Findings and recommenda-tions are then documented in a test re-port; the test reports typically include clear guidelines in terms of driving and tigh-tening torques, pilot hole geometry, hole.
