Create a decorative appearance on your finished product—the head of these screws is painted.

These screws have a tall, domed head that provides a finished appearance. They're zinc plated to resist corrosion in wet environments.

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. Screws may be mildly magnetic.

These aluminum screws are lightweight and resist corrosion in wet environments. They have a flange that is wider and thicker than our other flanged screws, so they distribute pressure the best.

Comparable in diameter to a washer, the flange on these screws distributes 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.

Sharp internal teeth dig into surfaces to resist large amounts of vibration, while the smooth outside edge provides a finished look. Also known as Sems screws, the washer rotates freely but is permanently attached.
