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.

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws. Their tamper-resistant Torx drive (also known as a pin-in Torx drive) makes them difficult to remove without special tools.

These 18-8 stainless steel button head screws have good chemical resistance and may be mildly magnetic. The tamper-resistant hex drive (also known as a pin-in hex drive) makes them difficult to remove without special tools.

Stainless steel screws have excellent corrosion resistance in most environments.

The washer on these screws has sharp external teeth that dig into surfaces for maximum holding power and vibration resistance. Also known as Sems screws, the washer rotates freely but is permanently attached.

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.

A zinc plating provides mild corrosion resistance.

Stainless steel screws have excellent corrosion resistance in most environments.

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. A nylon patch bonded to the threads adds friction to prevent loosening from vibration.
