<p>ISO 3506-4 specifies the mechanical properties of tapping screws made from austenitic, martensitic and ferritic grades of corrosion-resistant stainless steels when tested at an ambient temperature range of 15 °C to 25 °C. Properties vary between higher and lower temperatures.</p>
<p>It applies to tapping screws with threads from ST2,2 up to and including ST8 in accordance with ISO 1478. It does not apply to screws with special properties such as weldability.</p>
<p>ISO 3506-4 does not define corrosion or oxidation resistance in particular environments, however some information on materials for particular environments is given in an annex. </p>
<p>The aim of ISO 3506-4 is a classification into property classes of corrosion resistant stainless steel fasteners.</p>
