**Stainless Steel** ST9.5 is beyond the diameter range of ISO 3506-4, which is written up to ST8. ISO 3506-4 states that fasteners outside that range may still carry its property classes, provided they meet all applicable chemical, mechanical and physical requirements. If a property class is specified for ST9.5, its order-specific evidence must demonstrate those requirements. Note: the numerical tables in ISO 3506-4 do not extend to this size, so table values are not extrapolated.
