Are these good for fixing plastic to metal work

wanting to fix some plastic arches to the metal body of a car. Are these suitable?
Asked by: AndyS87
Hello AndyS87, The screws are capable of penetrating 5mm of light steel so may go through the metal work, however this is not their intended use so we cannot comment on suitability. Thank you for using Q and A, EC.
