A flange under the head distributes holding pressure and reduces the risk of crushing thin metal.

A free-rotating, permanently attached washer distributes holding pressure over a wider area than a flange and remains stationary to prevent scratching the material surface as you tighten the screw.

18-8 stainless steel screws have good chemical resistance.

More corrosion resistant than 18-8 stainless steel screws, these have excellent resistance to chemicals and salt water.

Made from 18-8 stainless steel, these screws are chemical resistant.

A rubber O-ring under the head creates a seal that withstands liquid and gas pressure.

Made from 410 stainless steel, these screws are strong, wear resistant, and mildly chemical resistant.

These steel screws have corrosion-resistant finishes.

These 18-8 stainless steel screws have a hardened steel drill point to penetrate steel and are coated to increase corrosion resistance.

Cutting their own pilot hole and threads as you fasten them into material, these metric screws have a drilling tip.

These steel screws are available with corrosion resistant finishes. A rubber-bonded washer compresses to form a watertight seal. They save you time and effort by drilling their own holes and fastening in a single operation.

Made from 410 stainless steel, these screws are strong, wear resistant, and mildly chemical resistant.

Known for their strength, these alloy steel screws are coated to provide corrosion resistance in wet environments.

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