About Rounded Head Screws

These screws have a decorative, domed head that sits above the surface when installed. They're angled under the head so they can be countersunk in a hole. Made from 18-8 stainless steel, they have good chemical resistance and are passivated for added protection against oxidation and corrosion. Screws may be mildly magnetic. Length is measured from the top of the bevel. DIN 966 is no longer an active specification and is superseded by ISO 7047. They are functionally equivalent with slight differences in head diameter and head height.
