316 Stainless Steel Button Head Hex Drive Screws

More corrosion resistant than 18-8 stainless steel screws, these button head screws have excellent resistance to chemicals and salt water. They are passivated for added protection against oxidation and corrosion. Screws may be mildly magnetic. Length is measured from under the head.
