A zinc plating provides mild corrosion resistance.

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Torx and Torx-Plus drives have more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

Made from alloy steel, these screws are three times stronger than standard steel button head Torx screws. A Torx-Plus drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Torx and Torx-Plus drives have more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

Made from stainless steel, these screws are chemical resistant and may be mildly magnetic.

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.

Made from stainless steel, these screws have good chemical resistance and may be mildly magnetic. All have a washer with 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.

These metric screws have a washer with 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.

A zinc plating provides mild corrosion resistance.

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.

Made from stainless steel, these screws have good chemical resistance and may be mildly magnetic. A curved washer protects delicate surfaces while providing constant tension. Also known as Square Cone Sems screws, the washer rotates freely but is permanently attached.

These stainless steel screws have good chemical resistance and may be mildly magnetic. The washer has sharp internal teeth that 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.

These metric screws have a washer with sharp internal teeth that dig into surfaces to resist large amounts of vibration. The smooth outside edge of the washer provides a finished look. Also known as Sems screws, the washer rotates freely but is permanently attached.

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws.

These button head screws have a unique drive that is sold only by McMaster-Carr, making them difficult to remove without a special driver bit. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

The extra-wide head distributes holding pressure to reduce the likelihood of crushing thin materials.

A tamper-resistant drilled spanner drive makes these screws difficult to remove without special tools. They're 18-8 stainless steel for good chemical resistance and may be mildly magnetic.

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.

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 steel screws are zinc plated to resist corrosion in wet environments.

Also known as wall plate screws, these screws are painted to match the color of a switch or outlet cover.
