Sealing Screws for Softwood and Plastic-Wood Composites
The neoprene-backed washer seals out contaminants. Also known as trim-head deck screws, they have a small flat head and slender shank to reduce the risk of splitting. They have a Type 17 auger point to penetrate softwood and plastic-wood composite decking material. Made from 18-8 stainless steel, they have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. Screws may be mildly magnetic. Length is measured from the top of the head.

Screws for Joining Sheet Metal to Wood
Able to penetrate overlapping sheets, these screws have a secure hold in wood. The hex head allows for a firm grip with a wrench, while a rubber washer provides a watertight seal. They're corrosion-resistant-coated steel to resist corrosion in wet environments and minimize reactions between dissimilar metals. Length is measured from under the washer.

Stainless Steel Hex Head Screws for Joining Plastic to Wood
18-8 stainless steel screws have good chemical resistance. They have a hex head for a secure grip with a wrench. Cutting wings under the head allow plastic to expand and contract without cracking. A washer made from aluminum and rubber bonded to steel adds a watertight seal. Length is measured from under the head.
