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.
