M4 304 Stainless Steel Flanged Button Head Screws
Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. All are passivated for added protection against oxidation and corrosion. Head height includes the flange. Length is measured from under the flange.
