M3 316 Stainless Steel Extra Truss Head Phillips Screws
316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. All are passivated for added protection against oxidation and corrosion. The extra-wide truss head distributes holding pressure to reduce the likelihood of crushing thin material. Screws may be mildly magnetic. Length is measured from under the head.
