These metric 316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. Screws may be mildly magnetic.

With a flange comparable in size to a washer, these metric screws distribute pressure better than standard flanged screws. Made from 316 stainless steel, they have excellent resistance to chemicals and salt water. Screws may be mildly magnetic.

These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.

Serrations under the head grip the material's surface for mild vibration resistance. The flange distributes pressure across the material's surface, eliminating the need for a washer.
