Simpson Strong Tie Strong Drive Wood Screws, 1-1/2 In., 25-pk.

Simpson Strong-Tie Strong-Drive SDS structural wood screws are heavy-duty fasteners engineered for demanding construction applications. These 1-1/2 inch screws feature a 1/4 inch diameter and 3/8 inch hex head, making them ideal for connector installations, wood-to-wood applications, and engineered wood projects. The Type-17 point design enables easy driving with no predrilling required, while serrated threads pull the fastener tightly into the material for maximum holding power.

Built with a patented double-barrier coating, these screws deliver superior corrosion resistance, making them suitable for weather-exposed projects and treated-wood applications where durability is essential. Each screw head is stamped with the Simpson Strong-Tie logo and fastener length for easy identification on the job site.
