Able to penetrate overlapping sheets, these screws have alternating high-low threads for a strong hold in wood. A rubber washer provides a watertight seal.

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

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.

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

Serrations under the head act as a brake to prevent overtightening and damaging threads.

Also known as Tap-Flex screws, these are made from hardened steel to penetrate hard material. They have a five-edged shank that presses tightly against the material to form threads and resist loosening.

Also known as deck screws, these Phillips screws have a sharp point and narrow body to penetrate softwood and plastic-wood composite decking material.
